Subject: [Intel-wired-lan] [PATCH v5 08/14] be2net: Use irq_update_affinity_hint
Date: Tue, 20 Jul 2021 19:26:18 -0400	[thread overview]
Message-ID: <20210720232624.1493424-9-nitesh@redhat.com> (raw)
In-Reply-To: <20210720232624.1493424-1-nitesh@redhat.com>

The driver uses irq_set_affinity_hint() to update the affinity_hint mask
that is consumed by the userspace to distribute the interrupts. However,
under the hood irq_set_affinity_hint() also applies the provided cpumask
(if not NULL) as the affinity for the given interrupt which is an
undocumented side effect.

To remove this side effect irq_set_affinity_hint() has been marked
as deprecated and new interfaces have been introduced. Hence, replace the
irq_set_affinity_hint() with the new interface irq_update_affinity_hint()
that only updates the affinity_hint pointer.
