Register driver for threaded interrupts. By default the driver will attempt I/O completion from interrupt context (primary handler). Since the driver tracks per reply queue outstanding I/Os, it will schedule threaded ISR if there are any outstanding I/Os expected on that particular reply queue. Threaded ISR (secondary handler) will loop for I/O completion as long as there are outstanding I/Os (speculative method using same per reply queue outstanding counter) or it has completed some X amount of commands (something like budget).

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.
