   I'm just not sure why the patches are not merged or even rejected.
 
  Because ideally I want a Maintainer ack.  That's Doug Gilbert.

James 
The patches were discussed and the ACked by Doug in February and reviewed again

   I'm submitting patches to the Linux kernel for more than 10 years to
   various trees and  I can agree that these are not some  urgent fixes,
   but  this is the first time my effort is ignored for such long time by
   the maintainer.
 
  Well, OK, I trust martin, I'll override the lack of Maintainer ack if

Just to clarify, I didn't have a problem with Tomas' patch per se, it's
just that my patch won't apply on top of his.  I'll submit a v2 if you
