Subject: [PATCH 4.14 003/104] scsi: hpsa: fix selection of reply queue
Date: Tue, 14 Aug 2018 19:16:17 +0200 [thread overview]
Message-ID: <20180814171515.480060510@linuxfoundation.org> (raw)
In-Reply-To: <20180814171515.270692185@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ming Lei <ming.lei@redhat.com>
commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef upstream.
Since commit 84676c1f21e8 ("genirq/affinity: assign vectors to all
possible CPUs") we could end up with an MSI-X vector that did not have
any online CPUs mapped. This would lead to I/O hangs since there was no
CPU to receive the completion.
Retrieve IRQ affinity information using pci_irq_get_affinity() and use
this mapping to choose a reply queue.
