Of 9176 MODULE_DESCRIPTIONs in Linux, 21 start with "The ".
Does having that word add anything useful?
Amusingly 129 end with a period. I wonder what Jon Corbet would prefer
:-)

A few tell us what the module does.
"Measures" "Provides"....
Do we want "Implements" ??

232 start "Driver " and 214 are "Driver for"....
Should we have "Server for" ??

26 start "Linux" ... which seems a bit redundant
12 contain "for Linux". 67 mention linux in some way.
28 contain the word "kernel" - also redundant.
Only three (others) mention "Linux kernel"

drivers/pcmcia/cs.c:MODULE_DESCRIPTION("Linux Kernel Card Services");
fs/ksmbd/server.c:MODULE_DESCRIPTION("Linux kernel CIFS/SMB SERVER");
fs/orangefs/orangefs-mod.c:MODULE_DESCRIPTION("The Linux Kernel VFS interface to ORANGEFS");

hmmm.. 192 contain the word "module". Fortunately none say
"Linux kernel module for ..."
I would have found that to be a step too far.

I'd like to suggest

"Implements Server for NFS - v2, 3, v4.{0,1,2}"

But that would require excessive #ifdef magic to get right.

A small part of me wants to suggest:

"nfsd"

but maybe I'm just in a whimsical mood today.
