Merge tag 'xfs-5.13-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong: "The notable user-visible addition this cycle is ability to remove space from the last AG in a filesystem. This is the first of many changes needed for full-fledged support for shrinking a filesystem. Still needed are (a) the ability to reorganize files and metadata away from the end of the fs; (b) the ability to remove entire allocation groups; (c) shrink support for realtime volumes; and (d) thorough testing of (a-c). There are a number of performance improvements in this code drop: Dave streamlined various parts of the buffer logging code and reduced the cost of various debugging checks, and added the ability to pre-create the xattr structures while creating files. Brian eliminated transaction reservations that were being held across writeback (thus reducing livelock potential. Other random pieces: Pavel fixed the repetitve warnings about deprecated mount options, I fixed online fsck to behave itself when a readonly remount comes in during scrub, and refactored various other parts of that code, Christoph contributed a lot of refactoring this cycle. The xfs_icdinode structure has been absorbed into the (incore) xfs_inode structure, and the format and flags handling around xfs_inode_fork structures has been simplified. Chandan provided a number of fixes for extent count overflow related problems that have been shaken out by debugging knobs added during 5.12. Summary: - Various minor fixes in online scrub. - Prevent metadata files from being automatically inactivated. - Validate btree heights by the computed per-btree limits. - Don't warn about remounting with deprecated mount options. - Initialize attr forks at create time if we suspect we're going to need to store them. - Reduce memory reallocation workouts in the logging code. - Fix some theoretical math calculation errors in logged buffers that span multiple discontig memory ranges but contiguous ondisk regions. - Speedups in dirty buffer bitmap handling. - Make type verifier functions more inline-happy to reduce overhead. - Reduce debug overhead in directory checking code. - Many many typo fixes. - Begin to handle the permanent loss of the very end of a filesystem. - Fold struct xfs_icdinode into xfs_inode. - Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx ioctl. - Remove a broken directory block format check from online scrub. - Fix a bug where we could produce an unnecessarily tall data fork btree when creating an attr fork. - Fix scrub and readonly remounts racing. - Fix a writeback ioend log deadlock problem by dropping the behavior where we could preallocate a setfilesize transaction. - Fix some bugs in the new extent count checking code. - Fix some bugs in the attr fork preallocation code. - Refactor if_flags out of the incore inode fork data structure" * tag 'xfs-5.13-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (77 commits) xfs: remove xfs_quiesce_attr declaration xfs: remove XFS_IFEXTENTS xfs: remove XFS_IFINLINE xfs: remove XFS_IFBROOT xfs: only look at the fork format in xfs_idestroy_fork xfs: simplify xfs_attr_remove_args xfs: rename and simplify xfs_bmap_one_block xfs: move the XFS_IFEXTENTS check into xfs_iread_extents xfs: drop unnecessary setfilesize helper xfs: drop unused ioend private merge and setfilesize code xfs: open code ioend needs workqueue helper xfs: drop submit side trans alloc for append ioends xfs: fix return of uninitialized value in variable error xfs: get rid of the ip parameter to xchk_setup_* xfs: fix scrub and remount-ro protection when running scrub xfs: move the check for post-EOF mappings into xfs_can_free_eofblocks xfs: move the xfs_can_free_eofblocks call under the IOLOCK xfs: precalculate default inode attribute offset xfs: default attr fork size does not handle device inodes xfs: inode fork allocation depends on XFS_IFEXTENT flag ...
