This patch adds functionality (in qgroup-verify.c) to compute bytecounts in subvolume quota groups. The original groups are read in and stored in memory so that after we compute our own bytecounts, we can compare them with those on disk. A print function is provided to do this comparison and show the results on the console. A 'qgroup check' pass is added to btrfsck. If any subvolume quota groups differ from what we compute, the differences for them are printed. We also provide an option '--qgroup-report' which will run only the quota check code and print a report on all quota groups. Other than making it possible to verify that our qgroup changes work correctly, this mode can also be used in xfstests for automated checking after qgroup tests. This patch does not address the following: - compressed counts are identical to non compressed, because kernel doesn't make the distinction yet. Adding the code to verify compressed counts shouldn't be hard at all though once kernel can do this. - It is only concerned with subvolume quota groups (like most of btrfs-progs).
