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. First we clean up a few weird things in XFS, then build a generic inode iteration function. Next, we convert the bulkstat ioctl to use it, then fix a few things from some of the code we saved from the old bulkstat inode iteration code. After that, we restructure the code slightly to support the inumbers functionality, and then port the inumbers ioctl to it too. Finally, we introduce a parallel inode walk feature to speed up quotacheck on large filesystems. The justification for this part is a little questionable since it needs further discovery of what hardware and software this works best on. It's also an open question of whether or not bulkstat could be optimized further. 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
