perf/core: Remove unused perf_cgroup_event_cgrp_time() function
The function was added by commit e5d1367f17ba ("perf: Add cgroup support") in 2011 and hasn't been used since then. Removing it fixes the following warning when building with Clang: kernel/events/core.c:696:19: error: unused function 'perf_cgroup_event_cgrp_time' [-Werror,-Wunused-function] Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Arnaldo Carvalho de Melo <acme@kernel.org> Cc: Douglas Anderson <dianders@chromium.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/20170523215132.189049-1-mka@chromium.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
