Merge tag 'block-5.5-2020-01-26' of git://git.kernel.dk/linux-block
Pull block fix from Jens Axboe:
"Unfortunately this weekend we had a few last minute reports, one was
for block.
The partition disable for zoned devices was overly restrictive, it can
work (and be supported) just fine for host-aware variants.
Here's a fix ensuring that's the case so we don't break existing users
of that"
