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_pptrsv8_r1 And the corresponding xfsprogs code is here https://github.com/allisonhenderson/xfsprogs/tree/xfsprogs_new_pptrs_v8_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 v7: xfs: Increase XFS_QM_TRANS_MAXDQS to 5 Modified xfs_dqlockn to sort dquotes before locking xfs: Hold inode locks in xfs_trans_alloc_dir Modified xfs_trans_alloc_dir to release locks before retrying trans allocation xfs: Hold inode locks in xfs_rename Modified xfs_rename to release locks before retrying trans allocation xfs: Expose init_xattrs in xfs_create_tmpfile Fixed xfs_generic_create to init attr tree xfs: add parent pointer support to attribute code Updated xchk_xattr_rec with new XFS_ATTR_PARENT flag xfs: Add parent pointer ioctl Include xfs_parent_utils.h in xfs_parent_utils.c to quiet compiler warnings Questions comments and feedback appreciated! Thanks all!
