    Well, this is part of the draft I am (heh) writing to document /proc
    Clarifications, additions, etc, very welcome as this is mostly 'guessing',
    since I haven't had a look to how mm works yet.

    slabinfo
    Information about the cache memory allocated for the various structures
    held in the system. Each structure type is called a slab, and each
    structure of that type is called an object.

    %s cache name
    (c_name)
    %d active objects
    %d total objects. These objects, albeit unused, are kept in the slab cache
    so we don't have grow that particular slab in case we need more objects
    -Following fields are only available #if SLAB_STATS-
    %d active slabs
    %d total slabs
    %d pages per slab
    %d the highest active object in the slab
    (c_high_mark)
    %d incremented each time the slab allocates space for an object
    (c_num_allocations)
    %d incremented each time the slab increases its size
    (c_grown)
    %d incremented each time the slab gets reaped (removed from the slab list)
    (c_reaped)
    %d incremented each time there's an error allocing or freeing kmem
    (c_errors)

    Dunno, but if SLAB_STATS still works it could be sueful.
