rcu: Remove "extern" from function declarations in kernel/rcu/rcu.h

teobaluta · paulmck · commit bd73a7f5cd43 · 2013-12-12T12:34:17.000-08:00
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.
