Subject: [PATCH v2 0/2] mm, thp: two THP splitting performance fixes
Date: Tue, 17 Jun 2014 18:37:57 -0400	[thread overview]
Message-ID: <1403044679-9993-1-git-send-email-Waiman.Long@hp.com> (raw)

 - Add a second patch to replace smp_mb() by smp_mb__after_atomic().

page splitting code to split its performance, particularly for the
x86 architecture.

Waiman Long (2):
  mm, thp: move invariant bug check out of loop in
    __split_huge_page_map
  mm, thp: replace smp_mb after atomic_add by smp_mb__after_atomic
