This method only changes a little code. But it holds the lock before the function jumps, which seems to violate the principle of minimizing the critical area.

use rcu to protect the function is fine, all related code is not from
IO fast path.

Please also notice this patch is impossible for stable backport because
of too much modifications.

Thanks,
Kuai
