Umm...  Works for me.  Let's do it this way, then:
	* rename those guys through the whole series
	* leave the "annotate the filesystems" bits to sit in a vfs.git
branch
	* slap trylock_super() + bugfixes I'd been doing today
(procfs and debugfs symlink removals racing with follow_link, oopsable;
double-copy in autofs dev_ioctl.c, with length not rechecked after
copying, theoretically oopsable + reasonably likely data leak) on top of queue
	* feed it through local tests and send an updated pull request later
tonight.
