Hi folks (mostly Dave), The inode-repair-improvements branch of the xfs-linux repository at: git://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git has just been updated for your review. This is all the online repair code, plus the new scrub functions that are enabled by infrastructure originally built for repair. This drop encompasses all of part 1 of online repair and sets us up for merging parent pointers as part 2. This code snapshot has been rebased against recent upstream, freshly QA'd, and is ready for people to examine. For veteran readers, the new snapshot can be diffed against the previous snapshot; and for new readers, this is a reasonable place to begin reading. For the best experience, it is recommended to pull this branch and walk the commits instead of trying to read any patch deluge. The only major changes here are the last few patches, which pin inode link counts to avoid integer overflows. The new head of the inode-repair-improvements branch is commit: e1f4597ca7e7 xfs: pin inodes that would otherwise overflow link count 184 new commits: Darrick J.
