From 425a17cbfff933c4cca4eeef5caa5926d198dd85 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 26 Jun 2017 12:20:58 +0200 Subject: [PATCH] nvme: Allocate queues for all possible CPUs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Unlike most drіvers that simply pass the maximum possible vectors to pci_alloc_irq_vectors NVMe needs to configure the device before allocting the vectors, so it needs a manual update for the new scheme of using all present CPUs.
