Hi all, Currently, we treat the garbage collection of post-EOF preallocations and copy-on-write preallocations as totally separate tasks -- different incore inode tags, different workqueues, etc. This is wasteful of radix tree tags and workqueue resources since we effectively have parallel code paths to do the same thing. Therefore, consolidate both functions under one radix tree bit and one workqueue function that scans an inode for both things at the same time. At the end of the series we make the scanning per-AG instead of per-fs so that the scanning can run in parallel. 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=eofblocks-consolidation fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=eofblocks-consolidation
