From ac0e5b7a6b93fb291b01fe1e951e3c16bcdd3503 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Tue, 16 Oct 2007 01:25:58 -0700 Subject: remove PAGE_GROUP_BY_MOBILITY Grouping pages by mobility can be disabled at compile-time. This was considered undesirable by a number of people. However, in the current stack of patches, it is not a simple case of just dropping the configurable patch as it would cause merge conflicts. This patch backs out the configuration option.
