From 6bdd9be628fa5f4dd14eb89ebddc12840d684277 Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Mon, 28 Jan 2008 17:20:26 -0600 Subject: [GFS2] Allocate gfs2_rgrpd from slab memory This patch moves the gfs2_rgrpd structure to its own slab memory. This makes it easier to control and monitor, and yields less memory fragmentation.
