[PATCHSET] misc annotations and fixes

[Al Viro <viro@ftp.linux.org.uk>]

	Assorted trivial stuff all over the place.  Please, pull from
for-linus branch in git.kernel.org/pub/scm/linux/kernel/git/viro/bird.git/
Hopefully I haven't fscked it up - first attempt at passing stuff that way...
	Individual patches will go to l-k (hopefully with all relevant Cc)
in a few minutes.
