[PATCH 0/3] Badblock tracking for gendisks

[Vishal Verma <vishal.l.verma@intel.com>]

Patch 1 copies badblock management code into a header of its own,
making it generally available. It follows common libraries of code
such as linked lists, where anyone may embed a core data structure
in another place, and use the provided accessor functions to
manipulate the data.

Patch 2 adds badblock tracking to gendisks (in preparation for use
by NVDIMM devices). Right now, it is turned on unconditionally - I'd
appreciate comments on if that is the right path.

Patch 3 converts md over to use the new badblocks 'library'. I have
done some pretty simple testing on this - created a raid 1 device,
made sure the sysfs entries show up, and can be used to add and view
badblocks. A closer look by the md folks would be nice here.

Vishal Verma (3):
  badblocks: Add core badblock management code
  block: Add badblock management for gendisks
  md: convert to use the generic badblocks code
