Merge tag 'xfs-for-linus-v3.14-rc1' of git://oss.sgi.com/xfs/xfs
Pull xfs update from Ben Myers:
"This is primarily bug fixes, many of which you already have. New
stuff includes a series to decouple the in-memory and on-disk log
format, helpers in the area of inode clusters, and i_version handling.
We decided to try to use more topic branches this release, so there
are some merge commits in there on account of that. I'm afraid I
didn't do a good job of putting meaningful comments in the first
couple of merges. Sorry about that. I think I have the hang of it
now.
For 3.14-rc1 there are fixes in the areas of remote attributes,
discard, growfs, memory leaks in recovery, directory v2, quotas, the
MAINTAINERS file, allocation alignment, extent list locking, and in
xfs_bmapi_allocate. There are cleanups in xfs_setsize_buftarg,
removing unused macros, quotas, setattr, and freeing of inode
clusters. The in-memory and on-disk log format have been decoupled, a
common helper to calculate the number of blocks in an inode cluster
has been added, and handling of i_version has been pulled into the
filesystems that use it.
- cleanup in xfs_setsize_buftarg
- removal of remaining unused flags for vop toss/flush/flushinval
- fix for memory corruption in xfs_attrlist_by_handle
- fix for out-of-date comment in xfs_trans_dqlockedjoin
- fix for discard if range length is less than one block
- fix for overrun of agfl buffer using growfs on v4 superblock
filesystems
- pull i_version handling out into the filesystems that use it
- don't leak recovery items on error
- fix for memory leak in xfs_dir2_node_removename
- several cleanups for quotas
- fix bad assertion in xfs_qm_vop_create_dqattach
- cleanup for xfs_setattr_mode, and add xfs_setattr_time
- fix quota assert in xfs_setattr_nonsize
- fix an infinite loop when turning off group/project quota before
user quota
- fix for temporary buffer allocation failure in xfs_dir2_block_to_sf
with large directory block sizes
- fix Dave's email address in MAINTAINERS
- cleanup calculation of freed inode cluster blocks
- fix alignment of initial file allocations to match filesystem
geometry
- decouple in-memory and on-disk log format
- introduce a common helper to calculate the number of filesystem
blocks in an inode cluster
- fixes for extent list locking
- fix for off-by-one in xfs_attr3_rmt_verify
- fix for missing destroy_work_on_stack in xfs_bmapi_allocate"
