Allison, Many, many thanks for your work on this patch series!! It's clearly been a very long slog. I've pulled in the first three patches, since I think those are clearly correct at this point. One minor change I've made was I fixed the spelling the flag, which I channged to EXT4_DISCARD_PARTIAL_PG_ZERO_UNMAPPED. (Sorry, but seeing MAPED everywhere was just grating on my nerves. :-) I didn't want to apply your 4th patch in the series since we're planning on reducing the usage of i_mutex in the fs/ext4 code proper, as recommended by Christoph. It wasn't immediately obvious to me whether it was safe to apply any of the patches after #4, so for now I've just merged in the first three, since they clearly fix real problems that show up in xfstests. Can you comment on whether patches #5, #6, and #7 depend on #4?
