Merge tag 'block-2023-01-06' of git://git.kernel.dk/linux
Pull block fixes from Jens Axboe:
"The big change here is obviously the revert of the pktcdvd driver
removal. Outside of that, just minor tweaks. In detail:
- Re-instate the pktcdvd driver, which necessitates adding back
bio_copy_data_iter() and the fops->devnode() hook for now (me)
- Fix for splitting of a bio marked as NOWAIT, causing either nowait
reads or writes to error with EAGAIN even if parts of the IO
completed (me)
- Fix for ublk, punting management commands to io-wq as they can all
easily block for extended periods of time (Ming)
- Removal of SRCU dependency for the block layer (Paul)"
