Subject: Re: [PATCH v6 00/11] ext4: port direct I/O to iomap infrastructure

Hi Matthew, could you do me a favor?  For the next (and hopefully
final :-) spin of this patch series, could you base it on the
ext4.git's master branch.  Then pull in Darrick's iomap-for-next
branch, and then apply your patches on top of that.

I attempted to do this with the v6 patch series --- see the tt/mb-dio
branch --- and I described on another e-mail thread, I appear to have
screwed up that patch conflicts, since it's causing a failure with
diroead-nolock using a 1k block size.  Since this wasn't something
that worked when you were first working on the patch set, this isn't
something I'm going to consider blocking, especially since a flay test
failure which happens 7% of the time, and using dioread_nolock with a
sub-page blocksize isn't something that is going to be all that common
(since it wasn't working at all up until now).

Still, I'm hoping that either Ritesh or you can figure out how my
simple-minded handling of the patch conflict between your and his
patch series can be addressed properly.

Thanks!!
