Subject: [PATCH net-next v2 0/2] add benchmark selftest and optimization for ptr_ring

Patch 1: add a selftest app to benchmark the performance
         of ptr_ring.
Patch 2: make __ptr_ring_empty() checking more reliable
         and use the just added selftest to benchmark the
         performance impact.

V2: add patch 1 and add performance data for patch 2.

Yunsheng Lin (2):
  selftests/ptr_ring: add benchmark application for ptr_ring
  ptr_ring: make __ptr_ring_empty() checking more reliable
