Merge tag 'xfs-for-linus-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pul xfs updates from Dave Chinner: "There's a couple of small API changes to the core DAX code which required small changes to the ext2 and ext4 code bases, but otherwise everything is within the XFS codebase. This update contains: - A new sparse on-disk inode record format to allow small extents to be used for inode allocation when free space is fragmented. - DAX support. This includes minor changes to the DAX core code to fix problems with lock ordering and bufferhead mapping abuse. - transaction commit interface cleanup - removal of various unnecessary XFS specific type definitions - cleanup and optimisation of freelist preparation before allocation - various minor cleanups - bug fixes for - transaction reservation leaks - incorrect inode logging in unwritten extent conversion - mmap lock vs freeze ordering - remote symlink mishandling - attribute fork removal issues" * tag 'xfs-for-linus-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (49 commits) xfs: don't truncate attribute extents if no extents exist xfs: clean up XFS_MIN_FREELIST macros xfs: sanitise error handling in xfs_alloc_fix_freelist xfs: factor out free space extent length check xfs: xfs_alloc_fix_freelist() can use incore perag structures xfs: remove xfs_caddr_t xfs: use void pointers in log validation helpers xfs: return a void pointer from xfs_buf_offset xfs: remove inst_t xfs: remove __psint_t and __psunsigned_t xfs: fix remote symlinks on V5/CRC filesystems xfs: fix xfs_log_done interface xfs: saner xfs_trans_commit interface xfs: remove the flags argument to xfs_trans_cancel xfs: pass a boolean flag to xfs_trans_free_items xfs: switch remaining xfs_trans_dup users to xfs_trans_roll xfs: check min blks for random debug mode sparse allocations xfs: fix sparse inodes 32-bit compile failure xfs: add initial DAX support xfs: add DAX IO path support ...
