From 5bf696dad4beecb6174e701c97e1f2574e6a2c96 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Wed, 28 Sep 2011 11:39:59 +0300 Subject: [PATCH] exofs: Rename struct ore_components comps => oc ore_components already has a comps member so this leads to things like comps->comps which is annoying. the name oc was already used in new code. So rename all old usage of ore_components comps => ore_components oc.
