Merge tag 'probes-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes updates from Masami Hiramatsu:
 "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"
