Hi Linus, Please pull this branch with changes for XFS for 6.10-rc1. Online repair feature continues to be expanded. Please refer to the section "New code for 6.10" for a brief description of changes added to Online repair. Also, we now support delayed allocation for realtime devices which have an extent size that is equal to filesystem's block size. We did find a regression late in the development cycle (https://lore.kernel.org/linux-xfs/87ttj8ircu.fsf@debian-BULLSEYE-live-builder-AMD64/). The regression is limited to files residing on an XFS realtime volume which has a Realtime extent size larger than filesystem's block size. I believe this configuration is rare and hence we can go ahead with merging the new code. Presently, A fix (https://lore.kernel.org/linux-xfs/20240517111355.233085-1-yi.zhang@xxxxxxxxxxxxxxx/T/#t) is being discussed. I did a test-merge with the main upstream branch as of a few minutes ago and didn't see any conflicts. Please let me know if you encounter any problems. The following changes since commit 0bbac3facb5d6cc0171c45c9873a2dc96bea9680: Linux 6.9-rc4 (2024-04-14 13:38:39 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-6.10-merge-6 for you to fetch changes up to 25576c5420e61dea4c2b52942460f2221b8e46e8: xfs: simplify iext overflow checking and upgrade (2024-05-03 11:20:06 +0530) ---------------------------------------------------------------- New code for 6.10: * Introduce Parent Pointer extended attribute for inodes. * Online Repair - Implement atomic file content exchanges i.e. exchange ranges of bytes between two files atomically. - Create temporary files to repair file-based metadata. This uses atomic file content exchange facility to swap file fork mappings between the temporary file and the metadata inode. - Allow callers of directory/xattr code to set an explicit owner number to be written into the header fields of any new blocks that are created. This is required to avoid walking every block of the new structure and modify their ownership during online repair. - Repair - Extended attributes - Inode unlinked state - Directories - Symbolic links - AGI's unlinked inode list. - Parent pointers. - Move Orphan files to lost and found directory. - Fixes for Inode repair functionality. - Introduce a new sub-AG FITRIM implementation to reduce the duration for which the AGF lock is held. - Updates for the design documentation. - Use Parent Pointers to assist in checking directories, parent pointers, extended attributes, and link counts. * Bring back delalloc support for realtime devices which have an extent size that is equal to filesystem's block size. * Improve performance of log incompat feature handling. * Fixes - Prevent userspace from reading invalid file data due to incorrect. updation of file size when performing a non-atomic clone operation. - Minor fixes to online repair. - Fix confusing return values from xfs_bmapi_write(). - Fix an out of bounds access due to incorrect h_size during log recovery. - Defer upgrading the extent counters in xfs_reflink_end_cow_extent() until we know we are going to modify the extent mapping. - Remove racy access to if_bytes check in xfs_reflink_end_cow_extent(). - Fix sparse warnings. * Cleanups - Hold inode locks on all files involved in a rename until the completion of the operation. This is in preparation for the parent pointers patchset where parent pointers are applied in a separate chained update from the actual directory update. - Compile out v4 support when disabled. - Cleanup xfs_extent_busy_clear(). - Remove unused flags and fields from struct xfs_da_args. - Remove definitions of unused functions. - Improve extended attribute validation. - Add higher level directory operations helpers to remove duplication of code. - Cleanup quota (un)reservation interfaces.
