#     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)"
#     
#     * tag 'block-2023-01-06' of git://git.kernel.dk/linux:

#       Revert "block: bio_copy_data_iter"
#       ublk: honor IO_URING_F_NONBLOCK for handling control command
#       block: don't allow splitting of a REQ_NOWAIT bio
