Hi all, I noticed from profiling xfs_scrub that the program spent a significant amount of time in phase 3 rendering descriptive strings in case we found an error and needed to report where we found them. Most of the time there aren't going to be errors, so we can reduce the runtime by 7-10% by only rendering those strings when we need to report an error. 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 xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=scrub-deferred-descriptions
