From 6ca84326c283e2f5d4ea920dec6f9d4272e4d124 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 17 May 2022 13:08:44 -0500 Subject: vhost: flush dev once during vhost_dev_stop When vhost_work_dev_flush returns all work queued at that time will have completed. There is then no need to flush after every vhost_poll_stop call, and we can move the flush call to after the loop that stops the pollers.
