Subject: [PATCH 0/2 v2] locking/qrwlock: Fix interrupt handling problem

v1->v2:
 - Add microbenchmark data for the second patch

This patch series contains 2 patches on qrwlock. The first one is just
a recap of the patch that I sent a few weeks ago. The second one is to
optimize the writer slowpath.

Waiman Long (2):
  locking/qrwlock: Fix bug in interrupt handling code
  locking/qrwlock: Don't contend with readers when setting _QW_WAITING
