The current array of struct qe_snum use 256*4 bytes for just keeping track of the free/used state of each index, and the struct layout means there's another 768 bytes of padding. If we just unzip that structure, the array of snum values just use 256 bytes, while the free/inuse state can be tracked in a 32 byte bitmap. So this reduces the .data footprint by 1760 bytes. It also serves as preparation for introducing another DT binding for specifying the snum values.

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.
