[ Upstream commit 7942b226e6b84df13b46b76c01d3b6e07a1b349e ]
When executing modinfo null_blk, there is an error in the description
of module parameter mbps, and the output information of cache_size is
incomplete.The output of modinfo before and after applying this patch
is as follows:
Before:
[...]
parm: cache_size:ulong
[...]
parm: mbps:Cache size in MiB for memory-backed device.
Default: 0 (none) (uint)
[...]
After:
[...]
parm: cache_size:Cache size in MiB for memory-backed device.
Default: 0 (none) (ulong)
[...]
parm: mbps:Limit maximum bandwidth (in MiB/s).
Default: 0 (no limit) (uint)
[...]
Fixes: 058efe000b ("null_blk: add module parameters for 4 options")

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.
