Hi all,
this series is the first part of cleaning up lifetimes and allocation of
the gendisk and request_queue structure. It adds a new interface to
allocate the disk and queue together for bio based drivers, and a helper
for cleanup/free them when a driver is unloaded or a device is removed.
May I ask what else you have in the pipe for the next steps?
The reason why I ask is that I am looking into some issues related to
lifecycle problems of gendisk/mmc, typically triggered at SD/MMC card
removal.
Together this removes the need to treat the gendisk and request_queue
as separate entities for bio based drivers.

This looks like a nice cleanup to me. Feel free to add, for the series:
