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_pptrsv5_r1 And the corresponding xfsprogs code is here https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v5_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 v4 xfs: Add new name to attri/d Removed 0 item count check from xlog_recover_attri_commit_pass2 Moved error reports into switch and converted to corruption reports xfs: Add xfs_verify_pptr Added const type to rec param Added xfs_attr3_leaf_flags needed by libxfs port xfs: extend transaction reservations for parent attributes Refactored xfs_calc_*_reservation routines Added helpers: xfs_calc_pptr_link_overhead xfs_calc_pptr_unlink_overhead xfs_calc_pptr_replace_overhead xfs: add parent attributes to link Removed unneeded defer cancel in xfs_link xfs: add parent attributes to symlink Removed unneeded defer cancel in xfs_symlink Removed unused macro XFS_SYMLINK_SPACE_RES Whitespace adjust Comment updates xfs: remove parent pointers in unlink Removed unused macro XFS_REMOVE_SPACE_RES xfs: Add parent pointers to rename Re-ordered this patch with cross rename Added old_rec feild in xfs_parent_defer Collapsed old_parent param in xfs_parent_defer_replace into old_rec feild Renamed ip's to dp's Re-ordered xfs_parent_defer_replace parameters xfs: Add parent pointers to xfs_cross_rename Updated calls to xfs_parent_defer_replace Questions comments and feedback appreciated! Thanks all!
