[PATCH 0/2] selftests/perf_events: fix test fail with optimizations

Posted by Eva Kurchatova 2 weeks, 1 day ago

This patchset fixes incorrect atomics and volatile usage, which caused
test failures when compiler optimizations were enabled previously.

Eva Kurchatova (2):
  selftests/perf_events: fix sigtrap_threads tests fail with -O2
  selftests/perf_events: replace volatile with READ_ONCE/WRITE_ONCE
