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?
In any case, are you happy with the SLAB one, and how they are propagated?
