SubjectRE: [PATCH 11/11] scsi: storvsc: Re-init stor_chns when a channel interrupt is re-assigned
Date
From: Andrea Parri (Microsoft) <parri.andrea@gmail.com> Sent: Sunday, April 5, 2020 5:15 PM
>
> For each storvsc_device, storvsc keeps track of the channel target CPUs
> associated to the device (alloced_cpus) and it uses this information to
> fill a "cache" (stor_chns) mapping CPU->channel according to a certain
> heuristic. Update the alloced_cpus mask and the stor_chns array when a
> channel of the storvsc device is re-assigned to a different CPU.
