Merge tag 'probes-fixes-v7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes fixes from Masami Hiramatsu:

 - Avoid temporary buffer truncation in match_command_args()

   Compare argument name, delimiter, and comm expression directly
   instead of formatting into a stack buffer to prevent false
   matching failures

 - Prevent out-of-bounds write in __trace_probe_log_err()

   Return early when trace_probe_log.argc is zero to prevent
   out-of-bounds access when constructing the formatted error
   command string

 - Fix potential underflow in LEN_OR_ZERO macro

   Ensure buffer length is greater than current position before
   subtraction to prevent unsigned size underflow when formatting
   print strings

 - Fix exact system name matching in eprobe_dyn_event_match()

   Check system name null-termination to avoid partial prefix
   matching when comparing event probe target system names
