This series brings forth the discussion we had tuesday in the EWG
meeting. <br>
<br>
Chelsio is proposing ofed developers use the linux-next-cherry-picks
directory for patches upstream and critical to a driver's
functionality, yet too big for the stable flow. Once OFED releases
with a new kernel that includes these patches, they will be removed
from the dir. <br>
