tools headers UAPI: Sync linux/prctl.h with the kernel sources to pick FUTEX knob
To pick the changes in:
63e8595c060a1fef ("futex: Allow to make the private hash immutable")
80367ad01d93ac78 ("futex: Add basic infrastructure for local task local hash")
That adds a FUTEX knob:
$ tools/perf/trace/beauty/prctl_option.sh > before
$ cp include/uapi/linux/prctl.h tools/perf/trace/beauty/include/uapi/linux/prctl.h
$ tools/perf/trace/beauty/prctl_option.sh > after

That now will be used to decode the syscall option and also to compose
filters, for instance:
