Arnaldo Carvalho de Melo d6dbfceec5 tools headers UAPI: Sync linux/prctl.h with the kernel sources 
To pick a new prctl introduced in:

  1446e1df9e ("kernel: Implement selective syscall userspace redirection")

That results in:

  $ tools/perf/trace/beauty/prctl_option.sh > before
  $ cp include/uapi/linux/prctl.h tools/include/uapi/linux/prctl.h
  $ tools/perf/trace/beauty/prctl_option.sh > after
  $ diff -u before after

   	[56] = "GET_TAGGED_ADDR_CTRL",
   	[57] = "SET_IO_FLUSHER",
   	[58] = "GET_IO_FLUSHER",
  +	[59] = "SET_SYSCALL_USER_DISPATCH",
   };
   static const char *prctl_set_mm_options[] = {
   	[1] = "START_CODE",
  $

Now users can do:

  # perf trace -e syscalls:sys_enter_prctl --filter "option==SET_SYSCALL_USER_DISPATCH"
^C#
  # trace -v -e syscalls:sys_enter_prctl --filter "option==SET_SYSCALL_USER_DISPATCH"
  New filter for syscalls:sys_enter_prctl: (option==0x3b) && (common_pid != 5519 && common_pid != 3404)
^C#

And also when prctl appears in a session, its options will be
translated to the string.
