block: clarify badblocks lifetime 2016-01-09T16:39:04+00:00 Dan Williams dan.j.williams@intel.com 2016-01-06T20:03:41+00:00 20a308f09e0d29ce6f5a4114cc476a998d569bfb 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().

badblocks: rename badblocks_free to badblocks_exit 2016-01-09T16:39:04+00:00 Dan Williams dan.j.williams@intel.com 2016-01-06T20:19:22+00:00 d3b407fb3f782bd915db64e266010ea30a2d381e For symmetry with badblocks_init() make it clear that this path only destroys incremental allocations of a badblocks instance, and does not free the badblocks instance itself.

badblocks: Add core badblock management code 2016-01-09T14:35:12+00:00 Vishal Verma vishal.l.verma@intel.com 2015-12-25T02:20:32+00:00 9e0e252a048b0ba5066f0dc15c3b2468ffe5c422 Take the core badblocks implementation from md, and make it generally available. This follows the same style as kernel implementations of linked lists, rb-trees etc, where you can have a structure that can be embedded anywhere, and accessor functions to manipulate the data. The only changes in this copy of the code are ones to generalize function/variable names from md-specific ones. Also add init and free functions.
