We currently have a helper ublk_queue_alloc_sqes which the ublk targets use to allocate SQEs for their own operations. However, as we move towards decoupled ublk_queues and ublk server threads, this helper does not make sense anymore. SQEs are allocated from rings, and we will have one ring per thread to avoid locking. Change the SQE allocation helper to ublk_io_alloc_sqes. Currently this still allocates SQEs from the io's queue's ring, but when we fully decouple threads and queues, it will allocate from the io's thread's ring instead.

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.
