[PATCH v3 00/13] block: add_disk() error handling stragglers

[Luis Chamberlain]

This v3 series has the following changes:

 o clarifies the nvdimm/btt fix to not call del_gendisk to be a proper
   fix regardless of kernel.
 o Adds reviewed-by tags
 o modified the __register_blkdev() changes so that we do not propagate
   the error code from add_disk() but instead we just cleanup the
   resources where needed, and update the documentation to reflect
   suggestions by Christoph
