Requests are included in the output I added, but are spelt "Requests". Limits and failures currently aren't, but adding them wouldn't be a bad idea at all. I'm also thinking off adding a "show umazone <x>" which would provide more detailed information about per-CPU caches, as we're currently looking at a potential UMA bug in a panic report on -stable. We'd pull some, but not all, of the logic from umastat.c. Robert N M Watson Computer Laboratory University of Cambridge
