nbd_config_put currently clears discard_sectors when unusing a device.
This is pretty odd behavior and different from the sector size
configuration which is simply left in places and then reconfigured when
nbd_set_size is as part of configuring the device. Change nbd_set_size
to clear discard_sectors if discard is not supported so that all the
queue limits changes are handled in one place.

pktcdvd sets max_hw_sectors on the queue of the underlying device that
it doesn't own (and doesn't reset it ever) since the driver was merged.
This can create all kinds of problems as the underlying driver doesn't
even know about it changing the limit.
As the state purpose is to not create I/Os larger than a single frame,
and pktcdvd never builds bios larger than that, just set REQ_NOMERGE
on the bios it submits so that largers I/Os never get built.
Note: I don't have packet writing hardware, so this is compile tested
only.

The current command UBLK_CMD_DEL_DEV won't return until the device is
released, this way looks more reliable, but makes userspace more
difficult to implement, especially about orders: unmap command
buffer(which holds one ublkc reference), ublkc close,
io_uring_file_unregister, ublkb close.
Add UBLK_CMD_DEL_DEV_ASYNC so that device deletion won't wait release,
then userspace needn't worry about the above order. Actually both loop
and nbd is deleted in this async way.

Firstly convert get_device() and put_device() into ublk_get_device()
and ublk_put_device().
Secondly annotate ublk_get_device() & ublk_put_device() as noinline
for trace, especially it is often to trigger device deletion hang
when incorrect order is used on ublkc mmap, ublkc close,
io_uring_sqe_unregister_file, ublkb close.

Currently zram allocates 2 physically contiguous pages per-CPU's
compression stream (we may have up to 4 streams per-CPU). Since those
buffers are per-CPU we allocate them from CPU hotplug path, which may have
higher risks of failed allocations on devices with fragmented memory.
Switch to virtually contiguous allocations - crypto comp does not seem
impose requirements on compression working buffers to be physically
contiguous.

The bio based I/O path complicates null_blk and also make various
data structures, including the per-command one way bigger than
required for the main request based interface. As the bio-based
path is mostly used by stacking drivers and simple memory based
drivers, and brd is a good example driver for the latter there is
no need to have a bio based path in null_blk. Remove the path
to simplify the driver and make future block layer API changes
simpler by not having to deal with the complex two API setup in
null_blk.
Note that the queue_mode field in struct nullb_device is kept as
that is simpler than having two different places to check the
value and fully open coding the debugfs helpers as the existing
ones won't work without a named struct member.

Call virtblk_read_limits and most of virtblk_probe_zoned_device before
allocating the gendisk and thus request_queue and make them read into
a queue_limits structure instead. Pass this initialized queue_limits
to blk_mq_alloc_disk to set the queue up with the right parameters
from the start and only leave a few final touches for zoned devices
to be done just before adding the disk.
