Pull rdma fixes from Doug Ledford:
 "Most are minor to important fixes.

  There is one performance enhancement that I took on the grounds that
  failing to check if other processes can run before running what's
  intended to be a background, idle-time task is a bug, even though the
  primary effect of the fix is to improve performance (and it was a very
  simple patch)"
