[openib-general] [PATCH 1/2][RFC] Implement resize of CQ

[Krishna Kumar]

Hi Hal,

I think others have answered it, but my 2 cents :

1. Current driver doesn't do this, it is a spec thing, a potential driver
   could do this in future. It is useful in the sense that the CQ is
   always atleast the size of the QP's that are using it in case the
   driver implements it, as Sean mentioned.

2. The patches that you are referring to are correct. If people agree that
   it is useful to have, I can regenerate against latest bits (that is if
   it doesn't apply).

thanks,

- KK
