Subject: [PATCH 1/2] percpu_counter: Make __percpu_counter_add an inline function on UP
Date: Thu, 28 Jan 2010 23:48:54 +1100 [thread overview]
Message-ID: <20100128124854.GF2996@kryten> (raw)
In-Reply-To: <1264628600.4283.2080.camel@laptop>
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.
