[Qemu-devel] [RFC PATCH 12/17] timer: remove replay clock probe in deadl


From: Pavel Dovgalyuk
Subject: [Qemu-devel] [RFC PATCH 12/17] timer: remove replay clock probe in deadline calculation
Date: Wed, 25 Apr 2018 15:46:43 +0300
User-agent: StGit/0.17.1-dirty

Ciro Santilli reported that commit a5ed352596a8b7eb2f9acce34371b944ac3056c4
breaks the execution replay. It happens due to the probing the clock
for the new instances of iothread.
However, this probing was made in replay mode for the timer lists that
are empty.
This patch removes clock probing in replay mode.
It is an artifact of the old version with another thread model.
