Message

This is the second series of driver conversions for add_disk()
error handling. You can find this set and the rest of the 7th set of
driver conversions on my 20210927-for-axboe-add-disk-error-handling
branch [0].

Changes on this v2 since the last first version of this
patch series:

  - rebased onto linux-next tag 20210927
  - nvme-multipath: used test_and_set_bit() as suggested by Keith Busch,         
    and justified this in the code with a comment as this race was not
    obvious
  - Added reviewed-by / Acked-by tags where one was provided
