Merge tag 'for-linus-v3.6-rc1' of git://oss.sgi.com/xfs/xfs
Pull xfs update from Ben Myers: "Numerous cleanups and several bug fixes. Here are some highlights: - Discontiguous directory buffer support - Inode allocator refactoring - Removal of the IO lock in inode reclaim - Implementation of .update_time - Fix for handling of EOF in xfs_vm_writepage - Fix for races in xfsaild, and idle mode is re-enabled - Fix for a crash in xfs_buf completion handlers on unmount." Fix up trivial conflicts in fs/xfs/{xfs_buf.c,xfs_log.c,xfs_log_priv.h} due to duplicate patches that had already been merged for 3.5. * tag 'for-linus-v3.6-rc1' of git://oss.sgi.com/xfs/xfs: (44 commits) xfs: wait for the write the superblock on unmount xfs: re-enable xfsaild idle mode and fix associated races xfs: remove iolock lock classes xfs: avoid the iolock in xfs_free_eofblocks for evicted inodes xfs: do not take the iolock in xfs_inactive xfs: remove xfs_inactive_attrs xfs: clean up xfs_inactive xfs: do not read the AGI buffer in xfs_dialloc until nessecary xfs: refactor xfs_ialloc_ag_select xfs: add a short cut to xfs_dialloc for the non-NULL agbp case xfs: remove the alloc_done argument to xfs_dialloc xfs: split xfs_dialloc xfs: remove xfs_ialloc_find_free Prefix IO_XX flags with XFS_IO_XX to avoid namespace colision. xfs: remove xfs_inotobp xfs: merge xfs_itobp into xfs_imap_to_bp xfs: handle EOF correctly in xfs_vm_writepage xfs: implement ->update_time xfs: fix comment typo of struct xfs_da_blkinfo. xfs: do not call xfs_bdstrat_cb in xfs_buf_iodone_callbacks ...
