From 0fbd80eac7bf2be0d6b0054a7f9195144d324f96 Mon Sep 17 00:00:00 2001 From: Jiahui Cen Date: Thu, 25 Feb 2021 18:03:57 +0800 Subject: [PATCH] block-backend: Stop retrying when draining Retrying failed requests when draining would make the draining hung. So it is better not to trigger the retry timer when draining. And after the virtual devices go back to work, they would retry those queued requests.
