Merge tag 'for-linus-v3.8-rc1' of git://oss.sgi.com/xfs/xfs
Pull xfs update from Ben Myers: "There is plenty going on, including the cleanup of xfssyncd, metadata verifiers, CRC infrastructure for the log, tracking of inodes with speculative allocation, a cleanup of xfs_fs_subr.c, fixes for XFS_IOC_ZERO_RANGE, and important fix related to log replay (only update the last_sync_lsn when a transaction completes), a fix for deadlock on AGF buffers, documentation and comment updates, and a few more cleanups and fixes. Details: - remove the xfssyncd mess - only update the last_sync_lsn when a transaction completes - zero allocation_args on the kernel stack - fix AGF/alloc workqueue deadlock - silence uninitialised f.file warning - Update inode alloc comments - Update mount options documentation - report projid32bit feature in geometry call - speculative preallocation inode tracking - fix attr tree double split corruption - fix broken error handling in xfs_vm_writepage - drop buffer io reference when a bad bio is built - add more attribute tree trace points - growfs infrastructure changes for 3.8 - fs/xfs/xfs_fs_subr.c die die die - add CRC infrastructure - add CRC checks to the log - Remove description of nodelaylog mount option from xfs.txt - inode allocation should use unmapped buffers - byte range granularity for XFS_IOC_ZERO_RANGE - fix direct IO nested transaction deadlock - fix stray dquot unlock when reclaiming dquots - fix sparse reported log CRC endian issue" Fix up trivial conflict in fs/xfs/xfs_fsops.c due to the same patch having been applied twice (commits eaef854335ce and 1375cb65e87b: "xfs: growfs: don't read garbage for new secondary superblocks") with later updates to the affected code in the XFS tree. * tag 'for-linus-v3.8-rc1' of git://oss.sgi.com/xfs/xfs: (78 commits) xfs: fix sparse reported log CRC endian issue xfs: fix stray dquot unlock when reclaiming dquots xfs: fix direct IO nested transaction deadlock. xfs: byte range granularity for XFS_IOC_ZERO_RANGE xfs: inode allocation should use unmapped buffers. xfs: Remove the description of nodelaylog mount option from xfs.txt xfs: add CRC checks to the log xfs: add CRC infrastructure xfs: convert buffer verifiers to an ops structure. xfs: connect up write verifiers to new buffers xfs: add pre-write metadata buffer verifier callbacks xfs: add buffer pre-write callback xfs: Add verifiers to dir2 data readahead. xfs: add xfs_da_node verification xfs: factor and verify attr leaf reads xfs: factor dir2 leaf read xfs: factor out dir2 data block reading xfs: factor dir2 free block reading xfs: verify dir2 block format buffers xfs: factor dir2 block read operations ...
