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_pptrsv7 And the corresponding xfsprogs code is here https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v7 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 v6: Andry had reported intermittent hangs on unmount while running stress tests. Reviewed and corrected unlocks in the case of error conditions. xfs: parent pointer attribute creation Fixed dp to unlock on error xfs: Hold inode locks in xfs_ialloc Fixed ip to unlock on create error xfs: add parent attributes to symlink Hold and release dp across pptr operation Questions comments and feedback appreciated! Thanks all!
