test_kmem_basic creates 100,000 negative dentries, with each one mapping to a slab object. After memory.high is set, these are reclaimed through the shrink_slab function call which reclaims all 100,000 entries. The test passes the majority of the time because when slab1 is calculated, it is often above 0, however, 0 is also an acceptable value.
