Subject: Re: [PATCH] netpoll: use non-BH variant of RCU

>     softirq: adjust error check
>     The error check for _local_bh_enable_ip() warns on both in_irq() and
>     irqs_disabled().  The check for in_irq() is necessary, because a hardirq
>     might well have interrupted bh execution, in which case it is simply
>     not possible for the hardirq to exclude the bh that got interrupted.
>     However, it is perfectly reasonable to disable bh while hardirqs are
>     disabled, and this in fact promotes common code.  This commit therefore
>     removes the irqs_disabled() check.
