storvsc uses the spinlock of the hv_device's primary channel to serialize modifications of stor_chns[] performed by storvsc_do_io() and storvsc_change_target_cpu(), when it could/should use a (per-) storvsc_device spinlock: this change untangles the synchronization mechanism for the (storvsc-specific) stor_chns[] array from the "generic" VMBus code and data structures, clarifying the scope of this synchronization mechanism.

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.
