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.
