Subject: tracing/filters: Fix MATCH_FRONT_ONLY filter matching
X-Git-Tag: v2.6.33-rc5~32^2~5
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=285caad415f459f336247932b4db95a571357a02;p=pandora-kernel.git

tracing/filters: Fix MATCH_FRONT_ONLY filter matching

MATCH_FRONT_ONLY actually is a full matching:

  # ./perf record -R -f -a -e lock:lock_acquire \
	--filter 'name ~rcu_*' sleep 1
  # ./perf trace
  (no output)

We should pass the length of the pattern string to strncmp().
