<div class='commit-subject'>Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma</div><div class='commit-msg'>Pull rdma fixes from Doug Ledford:
 "Second round of -rc fixes for 4.10.

  This -rc cycle has been slow for the rdma subsystem. I had already
  sent you the first batch before the Holiday break. After that, we kept
  only getting a few here or there. Up until this week, when I got a
  drop of 13 to one driver (qedr). So, here's the -rc patches I have. I
  currently have none held in reserve, so unless something new comes in,
  this is it until the next merge window opens.

  Summary:

   - series of iw_cxgb4 fixes to make it work with the drain cq API

   - one or two patches each to: srp, iser, cxgb3, vmw_pvrdma, umem,
     rxe, and ipoib

   - one big series (13 patches) for the new qedr driver"
