If you search for a leak then you'd have to check the first number in
each row: the number of active objects. Just look at the first row: it
documents the fields in the following rows.
If a number is huge and constantly increasing, then there is would be a
leak. Typically the inode, dentry and buffer_head caches are large, the
rest are small.
But: slab manages only small objects. I assume that nvidia allocates
pages with alloc_pages() and then plays with the page flags. This is the
layer below slab, you must look at /proc/meminfo to detect leaks.
