Subject: [PATCH 0/2] IB/rdmavt: cq ktrhead worker fix and API update

The kthread worker API has been improved in 4.9-rc1. The 2nd
patch uses the new functions and simplifies the kthread worker
creation and destroying.

I have found a possible race when working on the API conversion.
A proposed fix is in the 1st patch.

Both changes are compile tested only. I did not find an easy way
how to test them at runtime.

Petr Mladek (2):
  IB/rdmavt: Avoid queuing work into a destroyed cq kthread worker
  IB/rdmavt: Handle the kthread worker using the new API
