I do not think so. If you are interested, try to find "UBI take 2"
patches in lkml. Look how it looked liked. It consisted of many
independent units and units could access other units _only_ via
interfaces. I would do what you say there.

Read Teo's comments - I actually now agree with them. And after I had
changed UBI i got rid of several thousands lines of code, and the code
became simpler.

So, my argument is:
1. It makes no sense to introduce one more non-static function to _just_
encapsulate list_add_tail and _just_ for one caller.
2. It is _C_, it is _kernel_, and it is OK sometimes _not_ to follow
computer since rules.

Agreed, I'll add more comments, thanks.

I do not see any nice way to do this. If you suggest one, I will do.
