Sorry,
I think I know your meaning now.
Maybe we can unlock the spinlock before "schedule_timeout_interruptible"
and then lock again?
Like:
spin_unlock(...);
schedule_timeout_interruptible(1);
spin_lock(...);
Best wishes,

Thanks for reply :)
I think I should use "udelay(100000/HZ)" instead, do you think it is
right?
The delay is too long, please do not ignore that part of my critique
of your change.
You cannot delay so long under a lock, that's why the code is trying
to use a sleeping delay.
I'm not going to explain this problem another time.
