Anybody interested in auditing ACPI slab usage?
ftp.linux.org.uk/pub/people/viro/slab-leaks.patch
with CONFIG_DEBUG_SLAB_LEAK
creates /proc/slab_allocators
cheers,

Viro updated this patch so with CONFIG_KALLSYMS=y
it does the symbols in /proc. Format is now:
slab-name active-allocations caller
Here's what I see on my box:
