maintainerv4 cover fs: rework and optimize i_version handling in filesystems
From: Jeff Layton <[email protected]>
v4:
- fix SB_LAZYTIME handling in generic_update_time
- add memory barriers to patch to convert i_version field to atomic64_t
v3:
- move i_version handling functions to new header file
- document that the kernel-managed i_version implementation will appear to increase over time
- fix inode_cmp_iversion to handle wraparound correctly
v2:
- xfs should use inode_peek_iversion instead of inode_peek_iversion_raw
- rework file_update_time patch
- don't dirty inode when only S_ATIME is set and SB_LAZYTIME is enabled
- better comments and documentation
I think this is now approaching merge readiness.
Special thanks to Jan Kara and Dave Chinner who helped me tighten up the memory barriers in the final patch.
tl;dr: I think we can greatly reduce the cost of the inode->i_version counter, by exploiting the fact that we don't need to increment it if no one is looking at it. We can also clean up the code to prepare to eventually expose this value via statx().
Note that this set relies on a few patches that are in other trees. The full stack that I've been testing with is here:
https://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux.git/log/?h=iversion
The inode->i_version field is supposed to be a value that changes whenever there is any data or metadata change to the inode. Some filesystems use it internally to detect directory changes during readdir. knfsd will use it if the filesystem has MS_I_VERSION set. IMA will also use it to optimize away some remeasurement if it's available. NFS and AFS just use it to store an opaque change attribute from the server.
Only btrfs, ext4, and xfs increment it for data changes. Because of this, these filesystems must log the inode to disk whenever the i_version counter changes. That has a non-zero performance impact, especially on write-heavy workloads, because we end up dirtying the inode metadata on every write, not just when the times change.
It turns out though that none of these users of i_version require that it change on every change to the file. The only real requirement is that it be different if something changed since the last time we queried for it.
If we keep track of when something queries the value, we can avoid bumping the counter and an on-disk update when nothing else has changed if no one has queried it since it was last incremented.
This patchset changes the code to only bump the i_version counter when it's strictly necessary, or when we're updating the inode metadata anyway (e.g. when times change).
It takes the approach of converting the existing accessors of i_version to use a new API, while leaving the underlying implementation mostly the same. The last patch then converts the existing implementation to keep track of whether the value has been queried since it was last incremented. It then uses that to avoid incrementing the counter when it can.
With this, we reduce inode metadata updates across all 3 filesystems down to roughly the frequency of the timestamp granularity, particularly when it's not being queried (the vastly common case).
I can see measurable performance gains on xfs and ext4 with iversion enabled, when streaming small (4k) I/Os.
btrfs shows some slight gain in testing, but not quite the magnitude that xfs and ext4 show. I'm not sure why yet and would appreciate some input from btrfs folks.
My goal is to get this into linux-next fairly soon. If it shows no problems then we can look at merging it for 4.16, or 4.17 if all of the prequisite patches are not yet merged.

maintainerPATCH v4 1/19 fs: new API for handling inode->i_version
From: Jeff Layton <[email protected]>
Add a documentation blob that explains what the i_version field is, how it is expected to work, and how it is currently implemented by various filesystems.
We already have inode_inc_iversion. Add several other functions for manipulating and accessing the i_version counter. For now, the implementation is trivial and basically works the way that all of the open-coded i_version accesses work today.
Future patches will convert existing users of i_version to use the new API, and then convert the backend implementation to do things more efficiently.

Observers see
i_versionas a 64 number which never decreases.and the rest still makes perfect sense.
Thanks! Fixed in my tree. I'll not resend the set just for that though.
With this fixed the patch looks good to me. You can add:

Add a documentation blob that explains what the
i_versionfield is, how it is expected to work, and how it is currently implemented by various filesystems.We already have
inode_inc_iversion. Add several other functions for manipulating and accessing thei_versioncounter. For now, the implementation is trivial and basically works the way that all of the open-codedi_versionaccesses work today.Future patches will convert existing users of
i_versionto use the new API, and then convert the backend implementation to do things more efficiently.Signed-off-by Jeff Layton <[email protected]>--- fs/btrfs/file.c | 1 + fs/btrfs/inode.c | 1 + fs/btrfs/ioctl.c | 1 + fs/btrfs/xattr.c | 1 + fs/ext4/inode.c | 1 + fs/ext4/namei.c | 1 + fs/inode.c | 1 + include/linux/fs.h | 15 ---- include/linux/iversion.h | 205 +++++++++++++++++++++++++++++++++++++++++++++++ 9 files changed, 212 insertions(+), 15 deletions(-) create mode 100644 include/linux/iversion.hfs/btrfs/file.c +1

Merry Christmas, everyone! I got this in my stocking this morning.
Apparently this patch _really_ helps small I/Os on xfs on dax. See the attached email from kernel test robot. I got a couple of others about significant improvements in other tests too, but this one looks like the most significant.

maintainerPATCH v4 2/19 fs: don't take the i_lock in inode_inc_iversion
In reply to Jeff LaytonFrom: Jeff Layton <[email protected]>
The rationale for taking the i_lock when incrementing this value is lost in antiquity. The readers of the field don't take it (at least not universally), so my assumption is that it was only done here to serialize incrementors.
If that is indeed the case, then we can drop the i_lock from this codepath and treat it as a atomic64_t for the purposes of incrementing it. This allows us to use inode_inc_iversion without any danger of lock inversion.
Note that the read side is not fetched atomically with this change. The assumption here is that that is not a critical issue since the i_version is not fully synchronized with anything else anyway.

maintainerPATCH v4 5/19 afs: convert to new i_version API
In reply to Jeff LaytonFrom: Jeff Layton <[email protected]>
For AFS, it's generally treated as an opaque value, so we use the *_raw variants of the API here.
Note that AFS has quite a different definition for this counter. AFS only increments it on changes to the data, not for the metadata. We'll need to reconcile that somehow if we ever want to present this to userspace via statx.

Note that AFS has quite a different definition for this counter. AFS only increments it on changes to the data, not for the metadata.
This also applies to AFS directories: create, mkdir, unlink, rmdir, link, symlink, rename, and mountpoint creation/removal all bump the data version number on a directory by exactly one if they change it.

Thanks! I updated that part of the the commit log to read:

maintainerPATCH v4 10/19 nfs: convert to new i_version API
In reply to Jeff LaytonFrom: Jeff Layton <[email protected]>
For NFS, we just use the "raw" API since the i_version is mostly managed by the server. The exception there is when the client holds a write delegation, but we only need to bump it once there anyway to handle CB_GETATTR.

maintainerPATCH v4 16/19 fs: only set S_VERSION when updating times if necessary
In reply to Jeff LaytonFrom: Jeff Layton <[email protected]>
We only really need to update i_version if someone has queried for it since we last incremented it. By doing that, we can avoid having to update the inode if the times haven't changed.
If the times have changed, then we go ahead and forcibly increment the counter, under the assumption that we'll be going to the storage anyway, and the increment itself is relatively cheap.

Reviewed-by Jan Kara <[email protected]>
Thanks for the review! I've fixed it in my tree. I'll not re-post the set unless I have to make another significant change or someone requests it.
I did make one other change, and that was to drop the "const" qualifiers on the integer arguments in the new API. David Howells pointed out that they don't really help anything, and the prototypes look cleaner without them.
This set is now in linux-next as well, so I'm going to try to get this merged into v4.16, assuming no problems between now and the merge window.

maintainerPATCH v4 19/19 fs: handle inode->i_version more efficiently
In reply to Jeff LaytonFrom: Jeff Layton <[email protected]>
Since i_version is mostly treated as an opaque value, we can exploit that fact to avoid incrementing it when no one is watching. With that change, we can avoid incrementing the counter on writes, unless someone has queried for it since it was last incremented. If the a/c/mtime don't change, and the i_version hasn't changed, then there's no need to dirty the inode metadata on a write.
Convert the i_version counter to an atomic64_t, and use the lowest order bit to hold a flag that will tell whether anyone has queried the value since it was last incremented.
When we go to maybe increment it, we fetch the value and check the flag bit. If it's clear then we don't need to do anything if the update isn't being forced.
If we do need to update, then we increment the counter by 2, and clear the flag bit, and then use a CAS op to swap it into place. If that works, we return true. If it doesn't then do it again with the value that we fetch from the CAS operation.
On the query side, if the flag is already set, then we just shift the value down by 1 bit and return it. Otherwise, we set the flag in our on-stack value and again use cmpxchg to swap it into place if it hasn't changed. If it has, then we use the value from the cmpxchg as the new "old" value and try again.
This method allows us to avoid incrementing the counter on writes (and dirtying the metadata) under typical workloads. We only need to increment if it has been queried since it was last changed.

Since
i_versionis mostly treated as an opaque value, we can exploit that fact to avoid incrementing it when no one is watching. With that change, we can avoid incrementing the counter on writes, unless someone has queried for it since it was last incremented. If the a/c/mtime don't change, and thei_versionhasn't changed, then there's no need to dirty the inode metadata on a write.Convert the
i_versioncounter to anatomic64_t, and use the lowest order bit to hold a flag that will tell whether anyone has queried the value since it was last incremented.When we go to maybe increment it, we fetch the value and check the flag bit. If it's clear then we don't need to do anything if the update isn't being forced.
If we do need to update, then we increment the counter by 2, and clear the flag bit, and then use a CAS op to swap it into place. If that works, we return true. If it doesn't then do it again with the value that we fetch from the CAS operation.
On the query side, if the flag is already set, then we just shift the value down by 1 bit and return it. Otherwise, we set the flag in our on-stack value and again use cmpxchg to swap it into place if it hasn't changed. If it has, then we use the value from the cmpxchg as the new "old" value and try again.
This method allows us to avoid incrementing the counter on writes (and dirtying the metadata) under typical workloads. We only need to increment if it has been queried since it was last changed.

# first bad commit: [8618bff776758ebff5b55211e7b5a60a0fc119a5] fs: handle inode->i_version more efficiently
That's really strange. I'm afraid I have no idea what could be going on.
With NFS, we really just treat i_version as an opaque value, so I'm not sure how this patch in particular would affect anything there. We _do_ increment it if you have a write delegation in some cases, but not many servers hand those out.
ext4 will only touch the i_version field if you mount it with '-o iversion'. Are you doing that here?
Have you run the bisect more than once? Is this maybe an intermittent problem, and the bisect has landed on the wrong commit?
Thanks,

Since
i_versionis mostly treated as an opaque value, we can exploit that fact to avoid incrementing it when no one is watching. With that change, we can avoid incrementing the counter on writes, unless someone has queried for it since it was last incremented. If the a/c/mtime don't change, and thei_versionhasn't changed, then there's no need to dirty the inode metadata on a write.Convert the
i_versioncounter to anatomic64_t, and use the lowest order bit to hold a flag that will tell whether anyone has queried the value since it was last incremented.When we go to maybe increment it, we fetch the value and check the flag bit. If it's clear then we don't need to do anything if the update isn't being forced.
If we do need to update, then we increment the counter by 2, and clear the flag bit, and then use a CAS op to swap it into place. If that works, we return true. If it doesn't then do it again with the value that we fetch from the CAS operation.
On the query side, if the flag is already set, then we just shift the value down by 1 bit and return it. Otherwise, we set the flag in our on-stack value and again use cmpxchg to swap it into place if it hasn't changed. If it has, then we use the value from the cmpxchg as the new "old" value and try again.
This method allows us to avoid incrementing the counter on writes (and dirtying the metadata) under typical workloads. We only need to increment if it has been queried since it was last changed.

Ok, thanks. If you're seeing hangs then that might imply that we have some sort of excessive looping going on in the cmpxchg loops.

Since
i_versionis mostly treated as an opaque value, we can exploit that fact to avoid incrementing it when no one is watching. With that change, we can avoid incrementing the counter on writes, unless someone has queried for it since it was last incremented. If the a/c/mtime don't change, and thei_versionhasn't changed, then there's no need to dirty the inode metadata on a write.Convert the
i_versioncounter to anatomic64_t, and use the lowest order bit to hold a flag that will tell whether anyone has queried the value since it was last incremented.When we go to maybe increment it, we fetch the value and check the flag bit. If it's clear then we don't need to do anything if the update isn't being forced.
If we do need to update, then we increment the counter by 2, and clear the flag bit, and then use a CAS op to swap it into place. If that works, we return true. If it doesn't then do it again with the value that we fetch from the CAS operation.
On the query side, if the flag is already set, then we just shift the value down by 1 bit and return it. Otherwise, we set the flag in our on-stack value and again use cmpxchg to swap it into place if it hasn't changed. If it has, then we use the value from the cmpxchg as the new "old" value and try again.
This method allows us to avoid incrementing the counter on writes (and dirtying the metadata) under typical workloads. We only need to increment if it has been queried since it was last changed.

Ok, thanks. If you're seeing hangs then that might imply that we have some sort of excessive looping going on in the cmpxchg loops.
Could you apply the patch below and let me know if it causes either of the warnings to pop? That might at least point us in the right direction:
No new warnings with attached patch (except existing already lockdep:
"INFO: trying to register non-static key.").
Systemd timeouts on mounting /home but after entering rescue shell there

Only root (/) is froom NFS. The /home comes from sdcard (
/dev/mmcblk1).Quoted 2 lines
ext4 will only touch the
i_versionfield if you mount it with '-o iversion'. Are you doing that here?The /home is mounted by systemd from
/etc/fstab:

Have you run the bisect more than once? Is this maybe an intermittent problem, and the bisect has landed on the wrong commit?
I just run tests on commits around again (but not full bisect) on current next (next-20180108):

Best regards,
KrzysztofOk, thanks. If you're seeing hangs then that might imply that we have some sort of excessive looping going on in the cmpxchg loops.

Could you apply the patch below and let me know if it causes either of the warnings to pop? That might at least point us in the right direction:
No new warnings with attached patch (except existing already lockdep:
"INFO: trying to register non-static key.").
Yeah, I saw that in the original logs and it looks unrelated (and harmless).
Quoted 7 lines
Systemd timeouts on mounting /home but after entering rescue shell there
is no problem running mount /home:
Give root password for maintenance
(or press Control-D to continue):
root@odroidxu3:~# mount /home
[ 220.659331] EXT4-fs (mmcblk1p2): mounted filesystem with ordered data mode. Opts: (null)
Ok, thanks for testing it. So I guess we can probably rule out excessive looping in those functions as the issue.
To make sure I understand the problem: When systemd tries to do the initial mount of /home (which is an ext4 filesystem), it hangs. But once it drops to the shell, it works, if you do the mount by hand.
Is that correct?
If so, then is it possible to trigger sysrq commands during the hanging mount attempt? Maybe you could use e.g. sysrq-l, sysrq-w, etc. to determine what it's blocking on?
Thanks,

Yes, although it also timeouts on setting up /dev/ttySAC2 (serial console).

Yes, I have sysrq. Blocked state (w):

(Lack of) i_version handling in udf
In reply to Jeff LaytonJan,
Re: [PATCH v4 00/19] fs: rework and optimize i_version handling in filesystems
Quoted 14 lines · Jeff Layton
The
inode->i_versionfield is supposed to be a value that changes whenever there is any data or metadata change to the inode. Some filesystems use it internally to detect directory changes during readdir. knfsd will use it if the filesystem hasMS_I_VERSIONset. IMA will also use it to optimize away some remeasurement if it's available. NFS and AFS just use it to store an opaque change attribute from the server.Only btrfs, ext4, and xfs increment it for data changes. Because of this, these filesystems must log the inode to disk whenever the
i_versioncounter changes. That has a non-zero performance impact, especially on write-heavy workloads, because we end up dirtying the inode metadata on every write, not just when the times change.
Quoted 8 lines
It turns out though that none of these users of
i_versionrequire that it change on every change to the file. The only real requirement is that it be different if something changed since the last time we queried for it.If we keep track of when something queries the value, we can avoid bumping the counter and an on-disk update when nothing else has changed if no one has queried it since it was last incremented.
This happened to cross my radar, which made me think...is it a problem that the UDF driver does not have any references to i_version at all? I suppose R/W UDF is a small subset of the normal use cases, but the driver does try to support it.

This happened to cross my radar, which made me think...is it a problem that the UDF driver does not have any references to
