I spent some hours yesterday doing something like this manually, grepping for ogfs_glock() and its wrappers (ogfs_glock_i(), etc.). I'm writing some notes about it that I would like to append to your locking document (maybe just before the "Flaws" section?). I've also got some edits I would like to contribute to the doc, typos and clarifications, that sort of thing.
