The domain token sbitmaps are currently initialized to the device queue depth or 256, whichever is larger, and immediately resized to the maximum depth for that domain (256, 128, or 64 for read, write, and other, respectively). The sbitmap is never resized larger than that, so it's unnecessary to allocate a bitmap larger than the maximum depth. Let's just allocate it to the maximum depth to begin with. This will use marginally less memory, and more importantly, give us a more appropriate number of bits per sbitmap word.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
