Subject: [PATCH v2 00/13] block: add_disk() error handling stragglers

This is the last pending changes to address add_disk() error handling
completely. Changes on this v2 series:

  o dropped all patches which folks have said they'd pick up on their
    own trees or that I already see present on linux-next
  o rebased onto next-20211103
  o Added Reviewed-by tag by Dan Williams and addressed his recommended
    changes.
  o Re-added the nvdimm/blk changes given Dan Williams was not able to
    remove the driver in time for v5.16
  o Added new nvdimm/pmem driver changes, not sure how I missed addressing
    this before.
  o Just note that I keep Tetsuo Handa's patch in this series as it is
    a requirement for the __register_blkdev() changes.

You can find all these changes on my git tree:
