Message-Id: <7d016b6c725b88e5f61e21daaacf6c2e205537e0.1382962788.git.rashika.kheria@gmail.com> Date: Mon, 28 Oct 2013 17:54:39 +0530 From: Rashika Kheria <rashika.kheria@...il.com> To: opw-kernel@...glegroups.com, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Minchan Kim <minchan@...nel.org>, Jiang Liu <jiang.liu@...wei.com>, Nitin Gupta <ngupta@...are.org>, Jerome Marchand <jmarchand@...hat.com>, linux-kernel@...r.kernel.org Subject: [PATCH v6 3/3] Staging: zram: Fix decrement of variable by calling bdput() As suggested by Jerome Marchand "The code in reset_store get the block device (bdget_disk()) but it does not put it (bdput()) when it's done using it. The usage count is therefor incremented but never decremented." Hence, this patch introduces a call to bdput() to decrement the variable after usage.
