[PATCH v2 0/3] perf probe: Improve logs for long name string

Posted by Leo Yan 1 month, 2 weeks ago

The series [1] tries to use hashed symbol names for event names. This
can avoid failures due to long symbol names. Somehow, it is preferred to
specify a distinct event name when adding a probe.

This series follows up on the comment to improve the logs for long group
and event strings.

Changes from v1:
- Used a patch to add MAX_EVENT_NAME_LEN macro.
- Refined log for long event name failure to replace hashed event name
  (Masami).


Leo Yan (3):
  perf probe: Use the MAX_EVENT_NAME_LEN macro
  perf probe: Check group string length
  perf probe: Improve log for long event name failure
