Subject: [PATCH v1 0/8] block: add error handling for *add_disk*()

This series bumps from RFC to PATCH form for two reasons, one is that I
have run quite a bit of full blktests tests on this without finding
regressions. Second is that the only feedback from the first RFC was
from Bart asking for error injection support, and this series adds just
that.

Lemme know if you've spotted something stupid. You can find these
patches my linux-next 20210427-block-fixes-v8 branch. Yes, it is
using a slightly older linux-next, so I can respin, its just that
there were quite a bit of linux-next release which were *really*
*fscked* up lately, so I had to stick at least something slightly
stable.
