[PATCH v3 0/3] perf probe: Improve logs for long name string

[Leo Yan]

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 event
strings.

Changes from v2:
- Printed a more abstract syntax "EVENT=PROBEDEF" in log.
- Amended warning for adding suffix failure.

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).

  perf probe: Use the MAX_EVENT_NAME_LEN macro
  perf probe: Check group string length
  perf probe: Improve log for long event name failure
