Merge tag 'xfs-for-linus-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs updates from Dave Chinner: "A pretty average collection of fixes, cleanups and improvements in this request. Summary: - fixes for mount line parsing, sparse warnings, read-only compat feature remount behaviour - allow fast path symlink lookups for inline symlinks. - attribute listing cleanups - writeback goes direct to bios rather than indirecting through bufferheads - transaction allocation cleanup - optimised kmem_realloc - added configurable error handling for metadata write errors, changed default error handling behaviour from "retry forever" to "retry until unmount then fail" - fixed several inode cluster writeback lookup vs reclaim race conditions - fixed inode cluster writeback checking wrong inode after lookup - fixed bugs where struct xfs_inode freeing wasn't actually RCU safe - cleaned up inode reclaim tagging" * tag 'xfs-for-linus-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: (39 commits) xfs: fix warning in xfs_finish_page_writeback for non-debug builds xfs: move reclaim tagging functions xfs: simplify inode reclaim tagging interfaces xfs: rename variables in xfs_iflush_cluster for clarity xfs: xfs_iflush_cluster has range issues xfs: mark reclaimed inodes invalid earlier xfs: xfs_inode_free() isn't RCU safe xfs: optimise xfs_iext_destroy xfs: skip stale inodes in xfs_iflush_cluster xfs: fix inode validity check in xfs_iflush_cluster xfs: xfs_iflush_cluster fails to abort on error xfs: remove xfs_fs_evict_inode() xfs: add "fail at unmount" error handling configuration xfs: add configuration handlers for specific errors xfs: add configuration of error failure speed xfs: introduce table-based init for error behaviors xfs: add configurable error support to metadata buffers xfs: introduce metadata IO error class xfs: configurable error behavior via sysfs xfs: buffer ->bi_end_io function requires irq-safe lock ...
