perf tools: Increase MAX_EVENT_LENGTH
The name length of some trace events is longer than 30, like sys_enter_sched_get_priority_max and ext4_mb_discard_preallocations. Passing those events to perf-record will fail, try: # ./perf record -f -e syscalls:sys_enter_sched_get_priority_max -F 1 -a Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <4AB1F4AB.7050205@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
