From 20a308f09e0d29ce6f5a4114cc476a998d569bfb Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 6 Jan 2016 12:03:41 -0800 Subject: block: clarify badblocks lifetime The badblocks list attached to a gendisk is allocated by the driver which equates to the driver owning the lifetime of the object. Do not automatically free it in del_gendisk(). This is in preparation for expanding the use of badblocks in libnvdimm drivers and introducing devm_init_badblocks().
