Subject: Re: [PATCH v1 1/1] treewide: Align match_string() with
 sysfs_match_string()

Why do we think it's a good idea to increase and normalize the use of
double-underscore function names across the kernel, like
__match_string() in this case? It should mean "reserved for the
implementation, not to be called directly".

If it's to be used directly, it should be named accordingly, right?

Being in line with __sysfs_match_string() isn't a great argument alone,
because this adds three times the number of __match_string() calls than
there are __sysfs_match_string() calls. It's not a good model to follow.
Arguably both should be renamed.

BR,
Jani.
