This patch isn't just fixing overly long lines, but rather is introducing
kerneldoc comments and documenting things that weren't documented before.
That's fine, but please make the commit message accurately describe the patch.

If you're going to use kerneldoc comments, they should be correctly formatted.
This is not, since it's missing the word struct.  You can run this command to
see the kerneldoc warnings:

	./scripts/kernel-doc -v -none include/linux/watch_queue.h

Please make sure that comments provide useful information and don't just repeat
what the code says.
