Ok, I don't want to sound like I'm complaining :) but I updated
btrfs-progs to top of tree in git, installed it, and ran it on an 8TiB
filesystem that used to take 12H or so to check.
It finished in maybe 10mn, just 10mn! :)

This is great news, but can I trust that the program worked properly and
indeed that my filesystem is fully clean?
Or at this point if I'm not running --mode=lowmem, the regular mode is
really doesn't check much and only lowmem can do a proper check? (even
though it can't fix problems once it finds them)
Thanks
Marc
