Subject: rcu: Remove rcu_preempt_note_context_switch()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fa2b3b0a50949537ac95a521b3546e9a87dc0565;p=linux-beck.git

rcu: Remove rcu_preempt_note_context_switch()

With the removal of CONFIG_TINY_PREEMPT_RCU, rcu_preempt_note_context_switch()
is now an empty function.  This commit therefore eliminates it by inlining it.
