But that is orthogonal, isn't it? People will still expect to see it in
the old slabinfo file.

The current scheme for memory statistics is

/proc/meminfo contains global counters

/sys/devices/system/node/nodeX/meminfo

contains node specific counters.

The cgroups directory already contains various files. Adding a slabinfo
file would make sense and it could be found easily.

The sysfs hierachy /sys/kernel/slab could also show up there as a "slab"
directory under which all the details of the various caches would be
available and tunable. Very much in sync with the way the cgroups
directories operate.
