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