Subject: [patch 0/3] mm: memcontrol: performance fixlets for 3.18
Date: Wed, 24 Sep 2014 11:08:55 -0400	[thread overview]
Message-ID: <1411571338-8178-1-git-send-email-hannes@cmpxchg.org> (raw)

Hi Andrew,

here are 2 memcg performance fixlets for 3.18.  One improves uncharge
batching to reduce expensive res_counter ops and irq-toggling, the
other one allows THP charges to succeed under cache pressure.

Thanks!
