* git://oss.sgi.com:8090/xfs/xfs-2.6: (33 commits) [XFS] Don't use kmap in xfs_iozero. [XFS] Remove a bunch of unused functions from XFS. [XFS] Remove unused arguments from the XFS_BTREE_*_ADDR macros. [XFS] Remove unused header files for MAC and CAP checking functionality. [XFS] Make freeze code a little cleaner. [XFS] Remove unused argument to xfs_bmap_finish [XFS] Clean up use of VFS attr flags [XFS] Remove useless memory barrier [XFS] XFS sysctl cleanups [XFS] Fix assertion in xfs_attr_shortform_remove(). [XFS] Fix callers of xfs_iozero() to zero the correct range. [XFS] Ensure a frozen filesystem has a clean log before writing the dummy [XFS] Fix sub-block zeroing for buffered writes into unwritten extents. [XFS] Re-initialize the per-cpu superblock counters after recovery. [XFS] Fix block reservation changes for non-SMP systems. [XFS] Fix block reservation mechanism. [XFS] Make growfs work for amounts greater than 2TB [XFS] Fix inode log item use-after-free on forced shutdown [XFS] Fix attr2 corruption with btree data extents [XFS] Workaround log space issue by increasing XFS_TRANS_PUSH_AIL_RESTARTS ...
