From a4aa50db8865091c2b8a81be580c724dfbc6b8c6 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Fri, 7 Jun 2013 00:07:29 +0800 Subject: [PATCH] zram: kill unused zram_get_num_devices() Now there's no caller of zram_get_num_devices(), so kill it. And change zram_devices to static because it's only used in zram_drv.c.
