[PATCH 2/2] perf tools: Increase MAX_EVENT_LENGTH
From: Li Zefan
Date: Thu Sep 17 2009 - 04:36:17 EST
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
