Subject: [PATCH tip/core/rcu 16/16] rcu: Remove "extern" from function declarations in kernel/rcu/rcu.h

From: Teodora Baluta <teobaluta@...il.com>

Function prototypes don't need to have the "extern" keyword since this
is the default behavior. Its explicit use is redundant.  This commit
therefore removes them.
