2016-01-09block, badblocks: introduce devm_init_badblocksDan Williams
Provide a devres interface for initializing a badblocks instance. The pmem driver has several scenarios where it will be beneficial to have this structure automatically freed when the device is disabled / fails probe. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2016-01-09badblocks: rename badblocks_free to badblocks_exitDan Williams
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. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2016-01-09badblocks: Add core badblock management codeVishal Verma
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.
