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

From: Luis Chamberlain
Date: Wed Nov 03 2021 - 08:22:50 EST


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:
