I picked this up from Costa's slub memcg series. For fixing added warning by patch 4. == From: Glauber Costa <glommer@xxxxxxxxxxxxx> Subject: [PATCH 6/6] remove __must_check for res_counter_charge_nofail() Since we will succeed with the allocation no matter what, there isn't the need to use __must_check with it. It can very well be optional.
