Sure you can get the code. For now the test is fairly simple, will expand later. I have made a branch "mm_bulk_api" to avoid people using my repo getting compile errors (due to API not merged). Git repo[1] branch "mm_bulk_api": [1] https://github.com/netoptimizer/prototype-kernel/ The test kernel module is called "slab_bulk_test01", located under kernel/mm/slab_bulk_test01.c [2].
