Subject: [PATCH tip/core/rcu 2/7] rcu: Remove obsolete rcu_check_callbacks() header comment
In the deep past, rcu_check_callbacks() was only invoked if rcu_pending()
returned true. Which was fine, but these days rcu_check_callbacks()
is invoked unconditionally. This commit therefore removes the obsolete
sentence from the header comment.
