Subject: [GIT PULL] probes: Updates for v6.15

Hi Linus,

Probes updates for v6.15:

- probe-events: Add comments about entry data storing code to clarify
  where and how the entry data is stored for function return events.

- probe-events: Log error for exceeding the number of arguments to help
  user to identify error reason via tracefs/error_log file.

- selftests/ftrace: Improve the ftracetest to add followngs.
  . Expand the tprobe event test to check if it can correctly find
    the wrong format tracepoint name.
  . Add new syntax error test to check whether error_log correctly
    indicates a wrong character in the tracepoint name.
  . Add a new dynamic events argument limitation test case which checks
    max number of probe arguments.
