rcu: Use rcu_callback_t in call_rcu*() and friends
As we now have rcu_callback_t typedefs as the type of rcu callbacks, we should use it in call_rcu*() and friends as the type of parameters. This could save us a few lines of code and make it clear which function requires an rcu callbacks rather than other callbacks as its argument. Besides, this can also help cscope to generate a better database for code reading. Signed-off-by: Boqun Feng <boqun.feng@gmail.com> Signed-off-by: Paul E.
