The comment doesn't make anything clearer to me - you say what _scratch_mkfs
does but then you call _scratch_pool_mkfs. I could look, of course, but the
purpose of a comment is to make things clearer, not to make the reader wonder
why you wrote the comment. ;)
Its cut and paste error I will remove the comment.

Should these be more specific? I.e. do you want to do:
grep "^Data, " | grep -q $test_raid
because (at least in my version of btrfs-progs) there are two Data
lines in the df output (and two Metadata lines as well).
Which reminds me, has df output changed semi-recently, and do you need
to handle that? (Maybe that's what the non-specific grep accomplishes?)
Its generic enough to ignore minor format changes and check if
there is Data/Metadata and the given-raid. I can't think of anything
which break this.
Also, I'm curious (maybe I just haven't been keeping up) - was there a bug
where mkfs succeeded but didn't make the requested raid level?
thanks,
