Merge tag 'xfs-for-linus-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs update from Dave Chinner: "There's relatively little change in this update; it is mainly bug fixes, cleanups and more of the on-going libxfs restructuring and on-disk format header consolidation work. Details: - more on-disk format header consolidation - move some structures shared with userspace to libxfs - new per-mount workqueue to fix for deadlocks between nested loop mounted filesystems - various bug fixes for ENOSPC, stats, quota off and preallocation - a bunch of compiler warning fixes for set-but-unused variables - various code cleanups" * tag 'xfs-for-linus-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (24 commits) xfs: split metadata and log buffer completion to separate workqueues xfs: fix set-but-unused warnings xfs: move type conversion functions to xfs_dir.h xfs: move ftype conversion functions to libxfs xfs: lobotomise xfs_trans_read_buf_map() xfs: active inodes stat is broken xfs: cleanup xfs_bmse_merge returns xfs: cleanup xfs_bmse_shift_one goto mess xfs: fix premature enospc on inode allocation xfs: overflow in xfs_iomap_eof_align_last_fsb xfs: fix simple_return.cocci warning in xfs_bmse_shift_one xfs: fix simple_return.cocci warning in xfs_file_readdir libxfs: fix simple_return.cocci warnings xfs: remove unnecessary null checks xfs: merge xfs_inum.h into xfs_format.h xfs: move most of xfs_sb.h to xfs_format.h xfs: merge xfs_ag.h into xfs_format.h xfs: move acl structures to xfs_format.h xfs: merge xfs_dinode.h into xfs_format.h xfs: catch invalid negative blknos in _xfs_buf_find() ...
