Prakash Surya a9a7a01cf5 Add SPLAT test to exercise slab direct reclaim ... This test is designed to verify that direct reclaim is functioning as expected. We allocate a large number of objects thus creating a large number of slabs. We then apply memory pressure and expect that the direct reclaim path can easily recover those slabs. The registered reclaim function will free the objects and the slab shrinker will call it repeatedly until at least a single slab can be freed. Note it may not be possible to reclaim every last slab via direct reclaim without a failure because the shrinker_rwsem may be contended. For this reason, quickly reclaiming 3/4 of the slabs is considered a success. This should all be possible within 10 seconds. For reference, on a system with 2G of memory this test takes roughly 0.2 seconds to run. It may take longer on larger memory systems but should still easily complete in the alloted 10 seconds.
