https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v3.4.702012-01-21T08:33:41Zperf: Don't call release_callchain_buffers() if allocation fails2012-01-21T08:33:41ZNamhyung Kimnamhyung.kim@lge.com2012-01-20T01:12:45Zurn:sha1:fd45c15f13e754f3c106427e857310f3e0813951
When alloc_callchain_buffers() fails, it frees all of
entries before return. In addition, calling the
release_callchain_buffers() will cause a NULL pointer
dereference since callchain_cpu_entries is not set.

perf: Carve out callchain functionality2011-11-14T12:31:26ZBorislav Petkovborislav.petkov@amd.com2011-10-16T15:15:04Zurn:sha1:9251f904f95175b4a1d8cbc0449e748f9edd7629
Split the callchain code from the perf events core into
a new kernel/events/callchain.c file.
This simplifies a bit the big core.c
