Hi all, This next series refactors all the inode walking code in XFS into a single set of helper functions. The goal is to separate the mechanics of iterating a subset of inode in the filesystem from bulkstat. Next we introduce a parallel inode walk feature to speed up quotacheck on large filesystems. Finally, we port the existing bulkstat and inumbers ioctls in preparation for the next series. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. 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=parallel-iwalk xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=parallel-iwalk
