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

Thanks for the patches!
There are some things to improve there - I sent comments
in response to invididual patches.
