[PATCH v2 0/2] IB/rxe: Fix kernel panics when tearing down QPs

[PATCH v2 0/2] IB/rxe: Fix kernel panics when tearing down QPs

[Andrew Boyer]

This is a set of two patches that prevent kernel panics seen when tearing
down QPs. The second patch (holding refs in tasklets) might or might not be
needed once the first patch (waiting for tasklets to finish) is applied.
Feedback welcomed.

Update for v2:
 - Remove default initialization of idle in rxe_cleanup_task() per review

Andrew Boyer (2):
  IB/rxe: Wait for tasklets to finish before tearing down QP
  IB/rxe: Hold refs when running tasklets

Hi Andrew, I took these patches as well.  I had to fix up the second
one, so you might want to double check it.  Thanks.
