My eventual goal is to add support for multi memcg stock to solve the
charging cost of incoming networking traffic in multi-tenant
environment. In the cleanups my plan is to reduce the number of irq
disable operations in the most common paths and explore if for task
context we can do without any irq disabling operation (possibly by
separate stocks for in_task and !in_task contexts).
