When host_max_queue is set (> 0), set the Scsi_Host.host_tagset such that blk-mq will use a hostwide tagset over all SCSI host submission queues. This means that we may expose all submission queues and always use the hwq chosen by blk-mq. And since if sdebug_host_max_queue is set, sdebug_max_queue is fixed to the same value, we can simplify how sdebug_driver_template.can_queue is set.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
