From b6a4ae766e3133a4db73fabc81e522d1601cb623 Mon Sep 17 00:00:00 2001 From: Boqun Feng Date: Wed, 29 Jul 2015 13:29:38 +0800 Subject: 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 Signed-off-by: Paul E.
