From a49058fab2912296f068759490ac69ba43b43861 Mon Sep 17 00:00:00 2001 From: Gioh Kim Date: Thu, 4 Sep 2014 22:36:35 -0400 Subject: jbd/jbd2: use non-movable memory for the jbd superblock Sicne the jbd/jbd2 superblock is not released until the file system is unmounted, allocate the buffer cache from the non-moveable area to allow page migration and CMA allocations to more easily succeed.
