Merge tag 'xfs-5.5-merge-16' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull XFS updates from Darrick Wong: "For this release, we changed quite a few things. Highlights: - Fixed some long tail latency problems in the block allocator - Removed some long deprecated (and for the past several years no-op) mount options and ioctls - Strengthened the extended attribute and directory verifiers - Audited and fixed all the places where we could return EFSCORRUPTED without logging anything - Refactored the old SGI space allocation ioctls to make the equivalent fallocate calls - Fixed a race between fallocate and directio - Fixed an integer overflow when files have more than a few billion(!) extents - Fixed a longstanding bug where quota accounting could be incorrect when performing unwritten extent conversion on a freshly mounted fs - Fixed various complaints in scrub about soft lockups and unresponsiveness to signals - De-vtable'd the directory handling code, which should make it faster - Converted to the new mount api, for better or for worse - Cleaned up some memory leaks and quite a lot of other smaller fixes and cleanups. A more detailed summary: - Fill out the build string - Prevent inode fork extent count overflows - Refactor the allocator to reduce long tail latency - Rework incore log locking a little to reduce spinning - Break up the xfs_iomap_begin functions into smaller more cohesive parts - Fix allocation alignment being dropped too early when the allocation request is for more blocks than an AG is large - Other small cleanups - Clean up file buftarg retrieval helpers - Hoist the resvsp and unresvsp ioctls to the vfs - Remove the undocumented biosize mount option, since it has never been mentioned as existing or supported on linux - Clean up some of the mount option printing and parsing - Enhance attr leaf verifier to check block structure - Check dirent and attr names for invalid characters before passing them to the vfs - Refactor open-coded bmbt walking - Fix a few places where we return EIO instead of EFSCORRUPTED after failing metadata sanity checks - Fix a synchronization problem between fallocate and aio dio corrupting the file length - Clean up various loose ends in the iomap and bmap code - Convert to the new mount api - Make sure we always log something when returning EFSCORRUPTED - Fix some problems where long running scrub loops could trigger soft lockup warnings and/or fail to exit due to fatal signals pending - Fix various Coverity complaints - Remove most of the function pointers from the directory code to reduce indirection penalties - Ensure that dquots are attached to the inode when performing unwritten extent conversion after io - Deuglify incore projid and crtime types - Fix another AGI/AGF locking order deadlock when renaming - Clean up some quota typedefs - Remove the FSSETDM ioctls which haven't done anything in 20 years - Fix some memory leaks when mounting the log fails - Fix an underflow when updating an xattr leaf freemap - Remove some trivial wrappers - Report metadata corruption as an error, not a (potentially) fatal assertion - Clean up the dir/attr buffer mapping code - Allow fatal signals to kill scrub during parent pointer checks" * tag 'xfs-5.5-merge-16' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (198 commits) xfs: allow parent directory scans to be interrupted with fatal signals xfs: remove the mappedbno argument to xfs_da_get_buf xfs: remove the mappedbno argument to xfs_da_read_buf xfs: split xfs_da3_node_read xfs: remove the mappedbno argument to xfs_dir3_leafn_read xfs: remove the mappedbno argument to xfs_dir3_leaf_read xfs: remove the mappedbno argument to xfs_attr3_leaf_read xfs: remove the mappedbno argument to xfs_da_reada_buf xfs: improve the xfs_dabuf_map calling conventions xfs: refactor xfs_dabuf_map xfs: simplify mappedbno handling in xfs_da_{get,read}_buf xfs: report corruption only as a regular error xfs: Remove kmem_zone_free() wrapper xfs: Remove kmem_zone_destroy() wrapper xfs: Remove slab init wrappers xfs: fix attr leaf header freemap.size underflow xfs: fix some memory leaks in log recovery xfs: fix another missing include xfs: remove XFS_IOC_FSSETDM and XFS_IOC_FSSETDM_BY_HANDLE xfs: remove duplicated include from xfs_dir2_data.c ...
