It is certainly not through does the same method as SLAB, right ?
Writing to /proc/slabinfo gives me an I/O error
I assume it is something through sysfs, but schiming through the code
now, I can't find any per-cache tunables. Would you mind pointing me to
them?

The slab attributes in /sys/kernel/slab/<slabname>/<attr> can be modified
for some values. I think that could be the default method for the future
since it allows easy addition of new tunables as needed.

Christoph, would the following PoC patch be enough?
