[PATCH v2 0/2] vhost-scsi: Support worker ioctls

From: Mike Christie
Subject: [PATCH v2 0/2] vhost-scsi: Support worker ioctls
Date: Sun, 26 Nov 2023 18:28:32 -0600

The following patches allow users to configure the vhost worker threads
for vhost-scsi. With vhost-net we get a worker thread per rx/tx virtqueue
pair, but for vhost-scsi we get one worker for all workqueues. This
becomes a bottlneck after 2 queues are used.

In the upstream linux kernel commit:


we enabled the vhost layer to be able to create a worker thread and
attach it to a virtqueue.

This patchset adds support to vhost-scsi to use these ioctls so we are
no longer limited to the single worker.

- Make config option a bool instead of an int.
