我正在使用选项 IRQBALANCE_BANNED_CPUS=3e 运行 irqbalance，这意味着禁止除 cpu0 (111110) 之外的所有内容。现在我想确保它正常工作，但是当我检查文件 /proc/interrupts 时，我到处都看到一堆中断。如果中断 21、22、24 和 35 被禁止，为什么它们会转到其他 cpu？在更改 /etc/default/irqbalance 以包含 IRQBALANCE_BANNED_CPUS=3e 选项后，我确实重新启动了我的机器。我有没有错误地配置任何东西？是 irqbalance 不能正常工作吗？它是否在做它应该做的事情而我无法摆脱那些中断？我可以看到 irqbalance 正在使用 ps -ef 运行。

EDIT1：好吧，我现在更改为 IRQBALANCE_BANNED_CPUS=1，我得到了同样的结果。看来我的配置不起作用。：（ 但为什么？
