Sorry for noise. I see your patch in here[1] . I will modify

Hi Martijn
Hi Naresh,
I just sent a patch and cc'd you. I verified all the loop tests pass
again with that patch.
I think you want to say "without". I verified the ioctl_loop01 fails
with faf1d25440 ("loop: Clean up LOOP_SET_STATUS lo
ATUS_SETTABLE_FLAGS;
+ /* For flags that can't be cleared, use previous values. */
lo->lo_flags |= prev_lo_flags &~LOOP_SET_STATUS_CLEARABLE_FLAGS;

Thanks,

It may work. It may not.
Thanks for your explanation. I am more curious about the user scene of
this flag.
@Li, so how to design this test? In this test, we don't have complex
scene to test this automic unit.

Currently, when calling prctl(PR_SET_TIMERSLACK, arg2), arg2 is an
unsigned long value, arg2 will never < 0. Negative judgment is
meaningless, so remove it.
