Some definitions and members of struct tcmu_dev had misleading names. Examples: - ring_size was used for the size of mailbox + cmd ring + data area - CMDR_SIZE was used for size of mailbox + cmd ring I added the new definition MB_CMDR_SIZE (mailbox + command ring), changed CMDR_SIZE to hold the size of the command ring only and replaced in struct tcmu_dev the member ring_size with mmap_pages, because the member is now used in tcmu_mmap() only, where we need page count, not size. I also added the new struct tcmu_dev member 'cmdr' which is used to replace some occurences of '(void *)mb + CMDR_OFF' with 'udev->cmdr' for better readability.

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.
