Alexander Motin 139690d6c3 Really zero the zero page ... While switching abd_zero_buf allocation KPI I've missed the fact that kmem_zalloc() zeroed the allocation, while kmem_cache_alloc() does not. Add explicit bzero() after it. I don't think it should have caused real problems, but leaking one memory page content all over the pool is not good.
