xfs: sanitise sb_bad_features2 handling
We currently have to ensure that every time we update sb_features2 that we update sb_bad_features2. Now that we log and format the superblock in it's entirety we actually don't have to care because we can simply update the sb_bad_features2 when we format it into the buffer. This removes the need for anything but the mount and superblock formatting code to care about sb_bad_features2, and hence removes the possibility that we forget to update bad_features2 when necessary in the future.

xfs: consolidate superblock logging functions
We now have several superblock loggin functions that are identical except for the transaction reservation and whether it shoul dbe a synchronous transaction or not. Consolidate these all into a single function, a single reserveration and a sync flag and call it xfs_sync_sb().
Also, xfs_mod_sb() is not really a modification function - it's the operation of logging the superblock buffer. hence change the name of it to reflect this.
Note that we have to change the mp->m_update_flags that are passed around at mount time to a boolean simply to indicate a superblock update is needed.
commit 82a0064d5954394c55ef76cafdf563b2373cb21f

xfs: remove bitfield based superblock updates
When we log changes to the superblock, we first have to write them to the on-disk buffer, and then log that. Right now we have a complex bitfield based arrangement to only write the modified field to the buffer before we log it.
This used to be necessary as a performance optimisation because we logged the superblock buffer in every extent or inode allocation or freeing, and so performance was extremely important. We haven't done this for years, however, ever since the lazy superblock counters pulled the superblock logging out of the transaction commit fast path.
Hence we have a bunch of complexity that is not necessary that makes writing the in-core superblock to disk much more complex than it needs to be. We only need to log the superblock now during management operations (e.g. during mount, unmount or quota control operations) so it is not a performance critical path anymore.
As such, remove the complex field based logging mechanism and replace it with a simple conversion function similar to what we use for all other on-disk structures.
This means we always log the entirity of the superblock, but again because we rarely modify the superblock this is not an issue for log bandwidth or CPU time. Indeed, if we do log the superblock frequently, delayed logging will minimise the impact of this overhead.

xfs: fix implicit bool to int conversion
try_wait_for_completion returns bool so the wrapper function xfs_dqflock_nowait should probably also return bool and not int.

xfs: pass a 64-bit count argument to xfs_iomap_write_unwritten
The code is already ready for it, and the pnfs layout commit code expects to be able to pass a larger than 32-bit argument.

xfs: remove deprecated sysctls
xfsbufd_centisecs and age_buffer_centisecs were due for removal in 3.14. We forgot to do that - it's now well past time to remove these deprecated, unused sysctls.
commit aa5d95c1b57792119804c587b9a468019219d7e0

xfs: move xfs_bmap_finish prototype
This function is used libxfs code, but is implemented separately in userspace. Move the function prototype to xfs_bmap.h so that the prototype is shared even if the implementations aren't.
commit 9799b438ce21662fa173ffc0b30d93567a71dfa0

xfs: move struct xfs_bmalloca to libxfs
It no long is used for stack splits, so strip the kernel workqueue bits from it and push it back into libxfs/xfs_bmap.h so that it can be shared with the userspace code.
commit 5ebdc213ac02877e23fe7594d4b92b120488aac9
Author: Dave Chinner <[email protected]> Date: Fri Jan 9 10:46:31 2015 +1100
xfs: move xfs_types.h to libxfs
The types used by the core XFS code are common between kernel and userspace. xfs_types.h is duplicated in both kernel and userspace, so move it to libxfs along with all the other shared code.

xfs: move xfs_fs.h to libxfs
Ioctl API definitions are shared with userspace, so move the header file that defines them all to libxfs along with all the other code shared with userspace.
