Merge tag 'probes-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes updates from Masami Hiramatsu:
 "fprobe performance enhancement using rhltable:
   - use rhltable for fprobe_ip_table. The fprobe IP table has been
     converted to use an rhltable for improved performance when dealing
     with a large number of probed functions
   - Fix a suspicious RCU usage warning of the above change in the
     fprobe entry handler
   - Remove an unused local variable of the above change
   - Fix to initialize fprobe_ip_table in core_initcall()

  Performance optimization of fprobe by ftrace:
   - Use ftrace instead of fgraph for entry only probes. This avoids the
     unneeded overhead of fgraph stack setup
   - Also update fprobe selftest for entry-only probe
   - fprobe: Use ftrace only if CONFIG_DYNAMIC_FTRACE_WITH_ARGS or
     WITH_REGS is defined

  Cleanup probe event subsystems:
   - Allocate traceprobe_parse_context per probe instead of each probe
     argument parsing. This reduce memory allocation/free of temporary
     working memory
   - Cleanup code using __free()
   - Replace strcpy() with memcpy() in __trace_probe_log_err()"
