From 16828088f9e518158edecb6cde7e6fa38e4c889b Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Wed, 27 Oct 2010 21:30:09 -0400 Subject: [PATCH] ext4: use KMEM_CACHE instead of kmem_cache_create Also remove the SLAB_RECLAIM_ACCOUNT flag from the system zone kmem cache. This slab tends to be fairly static, so it shouldn't be marked as likely to have free pages that can be reclaimed.
