You can do a full scripted rename of up/down to the mutex API and then fix up the 100 places used by semaphores manually.
Again, folks, this only works for current in-tree kernel code. There are huge amounts of kernel code out-of-tree that still use up/down as (or potentially as) counting semaphores. Yes, some of that code is closed-source, but most of it is open-source stuff in people's "queues", such as the network patch-o-matic queue and other stuff. Lots of open-source out-of-tree drivers, too. Re-using the existing up()/down() names for a new purpose is a very very Bad Idea. Removing up()/down() entirely is not quite so bad, because at least then people will eventually notice the change. Leaving up()/down() as-is is really the most sensible option.
