RE: [PATCH v2 00/17] NTB: Add NTB hardware abstraction layer

[Allen Hubbe]

The patches in this set (v2) reply to a different message id than the 
cover letter I sent.  Please pardon my mistake.  Other than that, I hope 
the patches are ok this time around.

I wrote the cover letter, and then kept the same copy after fixing a few 
more things.  This has the email id of the cover letter generated before 
the fixes.

I should have instead copied the subject line and body into the new cover 
letter that was generated for the fixed patch set.  Now I have learned my 
lesson.

In addition to the email id, the diff stat is also for the patch set that 
I didn't send, before the last fixes.  The diff stat doesn't differ by 
much.  If anybody cares, here is the exact diff stat for the v2.

Finally, I've faked the email id of this message, so the patches appear to 
reply to this one.  I hope this will clean up any threading for people who 
use that feature in their email clients.
