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, shrink, nfs handles, verity, 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_pptrsv10 And the corresponding xfsprogs code is here https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v10 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 v9: Reordered patches 2 and 3 to be 6 and 7 xfs: Add xfs_verify_pptr moved parent pointer validators to xfs_parent xfs: Add parent pointer ioctl Extra validation checks for fs id added missing release for the inode use GFP_KERNEL flags for malloc/realloc reworked ioctl to use pptr listenty and flex array NEW xfs: don't remove the attr fork when parent pointers are enabled NEW directory lookups should return diroffsets too NEW xfs: move/add parent pointer validators to xfs_parent Questions comments and feedback appreciated! Thanks all!
