From 31fbea3ab94ea1bf537365e9340d64d216c3c3eb Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 25 May 2021 12:47:30 -0500 Subject: [PATCH] vhost-scsi: remove extra flushes The vhost work flush function was flushing the entire work queue, so there is no need for the double vhost_work_dev_flush calls in vhost_scsi_flush. And we do not need to call vhost_poll_flush for each poller because that call also ends up flushing the same work queue thread the vhost_work_dev_flush call flushed.
