Hi all, This series adds some logic to the inode scrubbers so that they can detect and deal with consistency errors between the link count and the per-inode unlinked list state. The helpers needed to do this are presented here because they are a prequisite for rebuildng directories, since we need to get a rebuilt non-empty directory off the unlinked list. Note that this patchset does not provide comprehensive reconstruction of the AGI unlinked list; that is coming in a subsequent patchset. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=repair-unlinked-inode-state --- Commits in this patchset: * xfs: ensure unlinked list state is consistent with nlink during scrub * xfs: update the unlinked list when repairing link counts --- fs/xfs/scrub/inode.c | 19 ++++++++++++++++++ fs/xfs/scrub/inode_repair.c | 45 ++++++++++++++++++++++++++++++++++++++++++ fs/xfs/scrub/nlinks_repair.c | 42 +++++++++++++++++++++++++++++++-------- fs/xfs/xfs_inode.c | 5 +---- fs/xfs/xfs_inode.h | 2 ++ 5 files changed, 100 insertions(+), 13 deletions(-)
