Even an atomic_long_t can wrap around and hence can result in duplicate
slab cache names. With my patch it is guaranteed that slab cache names
are unique. I'm not claiming that this patch is the best possible
solution but it's a working solution and a solution that doesn't require
too many changes to the ib_srpt driver.
