null_blk: Fix the description of the cache_size module argument
[ 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: 058efe000b31 ("null_blk: add module parameters for 4 options")
