[RFC 5/6] softirq: Add time accounting per-softirq type

2018-01-18 Thread Dmitry Safonov
Warning: not a merge-ready in any sense As discussed, softirqs will be deferred or processed right away according to how much time this type of softirq spent on CPU. This will improve e.g. handling of net-rx softirqs during packet storm and also give fair slice of cpu time for a userspace process
