Subject: [PATCH] add new irq migrate rule to avoid high cpu irq load
By the old irq migrate rule, the irqs cannot be moved if the adjustment_load will become smaller then
the min_load after moving irq. However, we can accept that the delta load become smaller after moving irq.

Subject: [PATCH 5/5] fix invalid pointer dereference banned_cpumask_from_ui
The memory of cpu_ban_string was release in sock_handle function,
so the banned_cpumask_from_ui will dereference an invalid memory.
Fix this issue by delay release memory.
Reproduce:
echo "settings cpus 0-3" | nc -U `find /var/run/irqbalance/ -name *sock`
