H A D | hinic_rx.c | 2d1e72f2 Fri Sep 03 10:24:28 CDT 2021 Nitesh Narayan Lal <nitesh@redhat.com> hinic: Use irq_set_affinity_and_hint()
The driver uses irq_set_affinity_hint() to:
- Set the affinity_hint which is consumed by the userspace for distributing the interrupts
- Enforce affinity
As per commit 352f58b0d9f2 ("net-next/hinic: Set Rxq irq to specific cpu for NUMA"), the hinic driver enforces its own affinity to bind IRQs to the local NUMA node. However, irq_set_affinity_hint() applying the provided cpumask as an affinity for the interrupt 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_set_affinity_and_hint() where the provided mask needs to be applied as the affinity and affinity_hint pointer needs to be set and replace with irq_update_affinity_hint() where only affinity_hint needs to be updated.
