Subject: Re: [PATCH V3 1/5] genirq/affinity: don't mark 'affd' as const
Date: Tue, 19 Feb 2019 08:42:27 +0800 [thread overview]
Message-ID: <tencent_6C5D1EC74B826B1E2F22293C@qq.com> (raw)

My lemote.com email is too weak, I'll stop top post because this time I've
cc-ed my gmail.
I've tested, this patch can fix the nvme problem, but it can't be applied
to 4.19 because of different context. And, I still think my original solution
(genirq/affinity: Assign default affinity to pre/post vectors) is correct.
There may be similar problems except nvme.

By applying the very same patch perhaps?
Thanks,
