#1220148 — [PATCH v3 0/2] ring_buffer: Make the benchmark slightly more safe

FromPetr Mladek <pmladek@suse.com>

Subject[PATCH v3 0/2] ring_buffer: Make the benchmark slightly more safe
Message-ID<q63Sh-5E0-3@gated-at.bofh.it>
These two patches fix potential races in the ring buffer benchmark.
The first two versions were reviewed as part of the patchset that
tried to convert some kthreads into the kthread worker API, see
http://thread.gmane.org/gmane.linux.kernel.api/13224/focus=13821

Changes in v3:

+ fixed several comments (suggested by Steven)
+ removed duplicate memory barrier (suggested by Steven)


Changes in v2:

+ keep the extra initialization; fix a race instead
+ move the setting of the current state (suggested by Steven)

Petr Mladek (2):
  ring_buffer: Do no not complete benchmark reader too early
  ring_buffer: Fix more races when terminating the producer in the
    benchmark
