At this point can you make your patch relative to whatever you used
last time (and remind me what it is)?  Or, can you give me a delta
between what you did last time and what you have now that has the
fixes?  The problem is that the patch touches so much of ext4 that
it's quite painful to maintain it in the ext4 patch queue --- it
either invalidates a large number of patches after the fact, or the
patch needs a huge amount of work to fix up patch conflicts if it is
applied afterwards --- and if it is placed in the middle of the patch
queue, both conditions apply.

So I will have to do a lot of fix ups either way.  So unless you're
willing to pull down the ext4 patch queue, at:

	git://repo.or.cz/ext4-patch-queue.git

... and worry about making it apply in place, it's probably easier for
you to give me delta's versus the last patch, and I'll integrate in
the changes by hand.
