Frederic Weisbecker 90c0e5fc7b perf lock: Always check min AND max wait time ... When a lock is acquired after beeing contended, we update the wait time statistics for the given lock. But if the min wait time is updated, we don't check the max wait time. This is wrong because the first time we update the wait time, we want to update both min and max wait time. Before: Name acquired contended total wait (ns) max wait (ns) min wait (ns) key 8 1 21656 0 21656 After: Name acquired contended total wait (ns) max wait (ns) min wait (ns) key 8 1 21656 21656 21656 Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp>		2010-05-09 13:45:30 +02:00
