[PATCH 1/2] percpu_counter: Make __percpu_counter_add an inlinefunction on UP

From: Anton Blanchard
Date: Thu Jan 28 2010 - 07:50:55 EST



Even though batch isn't used on UP, we may want to pass one in to keep the
SMP and UP code paths similar. Convert __percpu_counter_add to an inline
function so we wont get variable unused warnings if we do.
