Re: [PATCH 0/6 v7] ext4: fix 1k block bugs

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?

Thanks,

						- Ted
