Subject: inode: and a quick fixup for the fixup

inode: and a quick fixup for the fixup

This is too ugly to live long term but will do for the moment while I figure
out the proper way to deal with this and avoid things like the double search.

Possibly we need a unified 'bread' related operation that gets the contents
of a buffer into user space, by any means needed.

Something like

	bp = bfind(...)
	if (bp || !user) {
		if (bp == NULL)
			bread_no_lookup()
		update fields
		copy to user
		unlock
		return
	}
	issue raw copy to user page
