From: Allison Henderson <allison.henderson@xxxxxxxxxx> Hi all, This is the latest parent pointer attributes for xfs. The goal of this patch set is to add a parent pointer attribute to each inode. The attribute name containing the parent inode, generation, and directory offset, while the attribute value contains the file name. This feature will enable future optimizations for online scrub, or any other feature that could make use of quickly deriving an inodes path from the mount point. This set can be viewed on github here https://github.com/allisonhenderson/xfs/tree/xfs_new_pptrsv4_r3 And the corresponding xfsprogs code is here https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v4_r1 This set has been tested with the below parent pointers tests https://lore.kernel.org/fstests/20221012013812.82161-1-catherine.hoang@xxxxxxxxxx/T/#t Updates since v3: xfs: Add new name to attri/d Added check for new name length in xfs_attri_validate xfs: Increase XFS_DEFER_OPS_NR_INODES to 5 Typo fix xfs: Hold inode locks in xfs_rename Added helper xfs_iunlock_after_rename xfs: Expose init_xattrs in xfs_create_tmpfile only expose new param through xfs_create_tmpfile xfs: Increase rename inode reservation NEW xfs: extend transaction reservations for parent attributes Added xfs_*_log_count helpers Refactored xfs_calc_*_reservation helpers Added iovec payloads to overhead calculations Removed xfs_calc_parent_ptr_reservations xfs: parent pointer attribute creation Added xfs_pptr_calc_space_res Added xfs_create_space_res Added xfs_mkdir_space_res Typedef fix xfs: add parent attributes to link Added xfs_link_space_res xfs: add parent attributes to symlink Added xfs_symlink_space_res xfs: remove parent pointers in unlink Added xfs_remove_space_res xfs: Add parent pointers to xfs_cross_rename White space adjust xfs: Add parent pointers to rename Added xfs_rename_space_res rebase updates xfs: Filter XFS_ATTR_PARENT for getfattr Redone (new) xfs: Add parent pointer ioctl Removed XFS_IOC_ATTR_PARENT Commented xfs_pptr_info Whitespace adjustments Questions comments and feedback appreciated! Thanks all!
