v3 cover xfs: introduce struct xfs_da_geometry

Hi folks,

Version three of the patchset first posted here:

http://oss.sgi.com/pipermail/xfs/2014-May/036125.html

This version addresses the review comments so far.

Changelog:

Version 3:
- added xfs_da_unmount
- moved dir2 conversion functions to xfs_dir2_priv.h
- converted xfs_dir2_readdir.c to use local geo variables
- added a patch to remove newly redundant geometry fields from the struct xfs_da_state

Version 2:
- patch removing checks from xfs_da_read_buf() sent separately
- dropped patch adding xfs_da_geometry to the inode forks as it's not currently needed
- cleared up all the "XXX" notations added in the RFC series
- fixed several bugs in different patches as a result of incorrect conversions
- ensured each patch compiled and passes xfstests individually

PATCH v3 1/16 xfs: introduce directory geometry structure

From: Dave Chinner <[email protected]>

The directory code has a dependency on the struct xfs_mount to supply the directory block geometry. Block size, block log size, and other parameters are pre-caclulated in the struct xfs_mount or access directly from the superblock embedded in the struct xfs_mount.

Extract all of this geometry information out of the struct xfs_mount and superblock and place it into a new struct xfs_da_geometry defined by the directory code. Allocate and initialise it at mount time, and attach it to the struct xfs_mount so it canbe passed back into the directory code appropriately rather than using the struct xfs_mount.

PATCH v3 2/16 xfs: move directory block translatiosn to xfs_dir2_priv.h

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

Because they aren't actually part of the on-disk format, and so shouldn't be in xfs_da_format.h.

PATCH v3 3/16 xfs: kill XFS_DIR2...FIRSTDB macros

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

They are just simple wrappers around xfs_dir2_byte_to_db(), and we've already removed one usage earlier in the patch set. Kill the rest before we start removing the xfs_mount from conversion functions.

PATCH v3 12/16 xfs: reduce direct usage of mp->m_dir_geo

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

There are many places in the directory code were we don't pass the args into and so have to extract the geometry direct from the mount structure. Push the args or the geometry into these leaf functions so that we don't need to grab it from the struct xfs_mount.

This, in turn, brings use to the point where directory geometry is no longer a property of the struct xfs_mount; it is not a global property anymore, and hence we can start to consider per-directory configuration of physical geometries.

Start by converting the xfs_dir_isblock/leaf code - pass in the xfs_da_args and convert the readdir code to use xfs_da_args like the rest of the directory code to pass information around.

PATCH v3 13/16 xfs: remove mp->m_dir_geo from directory logging

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

We don't pass the xfs_da_args or the geometry all the way down to the directory buffer logging code, hence we have to use mp->m_dir_geo here. Fix this to use the geometry passed via the xfs_da_args, and convert all the directory logging functions for consistency.

PATCH v3 14/16 xfs: use xfs_da_geometry for block size in attr code

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

Rather than using the superblock value obtained through the xfs_mount.

PATCH v3 15/16 xfs: pass xfs_da_args to xfs_attr_leaf_newentsize

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

As it's only ever called from contexts where the xfs_da_args is present and contains all the information needed inside the args structure.

Hi folks,

Version three of the patchset first posted here:

http://oss.sgi.com/pipermail/xfs/2014-May/036125.html

This version addresses the review comments so far.

Quoted 8 lines

Changelog:

Version 3:
- added xfs_da_unmount
- moved dir2 conversion functions to xfs_dir2_priv.h
- converted xfs_dir2_readdir.c to use local geo variables
- added a patch to remove newly redundant geometry fields from the struct xfs_da_state

I don't see this bit anywhere in the series...

Brian

Quoted 10 lines

Version 2:
- patch removing checks from xfs_da_read_buf() sent separately
- dropped patch adding xfs_da_geometry to the inode forks as it's not currently needed
- cleared up all the "XXX" notations added in the RFC series
- fixed several bugs in different patches as a result of incorrect conversions
- ensured each patch compiled and passes xfstests individually

Oops, I got the wrong head commit when patchbombing. I've replied to the original patch 0 with a 17/16....

Cheers,

[PATCH 17/16] xfs: remove redundant geometry information from xfs_da_state

In reply to Dave Chinner

From: Dave Chinner <[email protected]>

It's carried in state->args->geo, so there's no need to duplicate it and use more stack space than necessary.
