Don't bother to look up a namespace just to drop if after retreiving the controller for the multipath case. Just look up a live controller for the subsystem directly. Signed-off-by:

According to the module parameter description for sgl_threshold, a value of 0 means that SGLs are disabled.

Lightnvm was an innovative idea to expose more low-level control over SSDs. But it failed to get properly standardized and remains a non-standarized extension to NVMe that requires vendor specific quirks for a few now mostly obsolete SSD devices. The standardized ZNS command set for NVMe has take over a lot of the approaches and allows for fully standardized operation. Remove the Linux code to support open channel SSDs as the few production deployments of the above mentioned SSDs are using userspace driver stacks instead of the fairly limited Linux support.

This will enable changing the virtual boundary of null blk devices. For now, null blk devices didn't have any restriction on the scatter/gather elements received from the block layer. Add a module parameter and a configfs option that will control the virtual boundary. This will enable testing the efficiency of the block layer bounce buffer in case a suitable application will send discontiguous IO to the given device.

swim3 only uses the virtual address of a bio to stash it into the data transfer using virt_to_bus. But the ppc32 virt_to_bus just uses the physical address with an offset.

Always use the track buffer that is already used for addresses outside the 16MB address capability of the floppy controller. This allows to remove a lot of code that relies on kernel virtual addresses. With this gone there is just a single place left that looks at the bio, which can be converted to memcpy_{from,to}_page, thus removing the need for the extra block-layer bounce buffering for highmem pages.
