Subject: [PATCH 119/414] tracing: Don't add flag strings when displaying
|
|
variable references
|
|
|
|
Variable references should never have flags appended when displayed -
|
|
prevent that from happening.
|
|
|
|
Before:
|
|
|
|
# cat /sys/kernel/debug/tracing/events/sched/sched_switch/trigger
|
|
hist:keys=next_pid:vals=hitcount:wakeup_lat=common_timestamp.usecs-$ts0.usecs:...
|
|
|
|
After:
|
|
|
|
hist:keys=next_pid:vals=hitcount:wakeup_lat=common_timestamp.usecs-$ts0:...
|
