Currently, each ublk server I/O handler thread initializes its own queue. However, as we move towards decoupled ublk_queues and ublk server threads, this model does not make sense anymore, as there will no longer be a concept of a thread having "its own" queue. So lift queue initialization out of the per-thread ublk_io_handler_fn and into a loop in ublk_start_daemon (which runs once for each device). There is a part of ublk_queue_init (ring initialization) which does actually need to happen on the thread that will use the ring; that is separated into a separate ublk_thread_init which is still called by each I/O handler thread.

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 reStructuredText 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.
