Merge tag 'probes-v6.3' of git://git./linux/kernel/git/trace/linux-trace

Pull kprobes updates from Masami Hiramatsu:

 - Skip negative return code check for snprintf in eprobe

 - Add recursive call test cases for kprobe unit test

 - Add 'char' type to probe events to show it as the character instead
   of value

 - Update kselftest kprobe-event testcase to ignore '__pfx_' symbols

 - Fix kselftest to check filter on eprobe event correctly

 - Add filter on eprobe to the README file in tracefs

 - Fix optprobes to check whether there is 'under unoptimizing' optprobe
   when optimizing another kprobe correctly

 - Fix optprobe to check whether there is 'under unoptimizing' optprobe
   when fetching the original instruction correctly

 - Fix optprobe to free 'forcibly unoptimized' optprobe correctly

  Note that the array can be applied to memory type fetchargs, you can not
  apply it to registers/stack-entries etc. (for example, '$stack1:x8[8]' is
  wrong, but '+8($stack):x8[8]' is OK.)

  String type is a special type, which fetches a "null-terminated" string from
  kernel space. This means it will fail and store NULL if the string container
  has been paged out. "ustring" type is an alternative of string for user-space.
