It also removes some intializations which are redundant with the code in kernel/events/core.c Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: http://lkml.kernel.org/r/1411559322-16548-7-git-send-email-eranian@google.com Cc: cebbert.lkml@gmail.com Cc: Arnaldo Carvalho de Melo <acme@kernel.org> Cc: jolsa@redhat.com Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@kernel.org> |
