[PATCH 3/3] nvme: allocate queues for all possible CPUs
From: Christoph Hellwig
Date: Mon Jun 26 2017 - 06:21:42 EST
Unlike most drÑvers 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.
