[PATCH 11/41] perf tools: Fix one of the probe events to exclude kernel

From: Arnaldo Carvalho de Melo
Date: Wed Aug 13 2014 - 18:49:35 EST


From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

When probing the kernel API the kernel should be excluded otherwise the
probe will fail for users with insufficient privilege to profile the
kernel.
