From 43801f6e4ee269cd76f601c2b1d79897ea4a892f Mon Sep 17 00:00:00 2001 From: Noah Watkins Date: Wed, 20 Jul 2011 17:05:57 -0600 Subject: [PATCH] staging: zram: make global var "devices" use unique name The global variable "devices" is too general to be global. This patch switches the name to be "zram_devices".
