Merge tag 'xfs-5.1-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong: "Here are a number of new features and bug fixes for 5.1 They've undergone a week's worth of fstesting and merge cleanly with master as of this morning Most of the changes center on improving metadata validation and fixing problems with online fsck, though there's also a new cache to speed up unlinked inode handling and cleanup of the copy on write code in preparation for future features Changes for Linux 5.1: - Fix online fsck to handle inode btrees correctly on 64k block filesystems - Teach online fsck to check directory and attribute names for invalid characters - Miscellanous fixes for online fsck - Introduce a new panic mask so that we can halt immediately on metadata corruption (for debugging purposes) - Fix a block mapping race during writeback - Cache unlinked inode list backrefs in memory to speed up list processing - Separate the bnobt/cntbt and inobt/finobt buffer verifiers so that we can detect crosslinked btrees - Refactor magic number verification so that we can standardize it - Strengthen ondisk metadata structure offset build time verification - Fix a memory corruption problem in the listxattr code - Fix a shutdown problem during log recovery due to unreserved finobt expansion - Fix a referential integrity problem where O_TMPFILE inodes were put on the unlinked list with nlink > 0 which would cause asserts during log recovery if the system went down immediately - Refactor the delayed allocation allocator to be more clever about the possibility that its mapping might be stale - Various fixes to the copy on write mechanism - Make CoW preallocation suitable for use even with writes that wouldn't otherwise require it - Refactor an internal API - Fix some statx implementation bugs - Fix miscellaneous compiler and static checker complaints" * tag 'xfs-5.1-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (70 commits) xfs: fix reporting supported extra file attributes for statx() xfs: fix backwards endian conversion in scrub xfs: fix uninitialized error variables xfs: rework breaking of shared extents in xfs_file_iomap_begin xfs: don't pass iomap flags to xfs_reflink_allocate_cow xfs: fix uninitialized error variable xfs: introduce an always_cow mode xfs: report IOMAP_F_SHARED from xfs_file_iomap_begin_delay xfs: make COW fork unwritten extent conversions more robust xfs: merge COW handling into xfs_file_iomap_begin_delay xfs: also truncate holes covered by COW blocks xfs: don't use delalloc extents for COW on files with extsize hints xfs: fix SEEK_DATA for speculative COW fork preallocation xfs: make xfs_bmbt_to_iomap more useful xfs: fix xfs_buf magic number endian checks xfs: retry COW fork delalloc conversion when no extent was found xfs: remove the truncate short cut in xfs_map_blocks xfs: move xfs_iomap_write_allocate to xfs_aops.c xfs: move stat accounting to xfs_bmapi_convert_delalloc xfs: move transaction handling to xfs_bmapi_convert_delalloc ..
