Subject: [GIT PULL] probes: Updates for v6.17

Linus,

Probes updates for v6.17:

 - Stack usage reduction for probe events:
   - Allocate string buffers from the heap for uprobe, eprobe, kprobe,
     and fprobe events to avoid stack overflow.
   - Allocate traceprobe_parse_context from the heap to prevent
     potential stack overflow.
   - Fix a typo in the above commit.

 - New features for eprobe and tprobe events:
   - Add support for arrays in eprobes.
   - Support multiple tprobes on the same tracepoint.

 - Improve efficiency:
   - Register fprobe-events only when it is enabled to reduce overhead.
   - Register tracepoints for tprobe events only when enabled to
     resolve a lock dependency.

 - Code Cleanup:
   - Add kerneldoc for traceprobe_parse_event_name() and __get_insn_slot().
   - Sort #include alphabetically in the probes code.
   - Remove the unused 'mod' field from the tprobe-event.
   - Clean up the entry-arg storing code in probe-events.

 - Selftest update
   - Enable fprobe events before checking enable_functions in selftests.
