commit e17ca57cf5e6d4c6d11eccca7daee853915a6eff
Author: Ian Jackson <ian.jackson@xxxxxxxxxxxxx>
Date: Thu May 28 18:24:49 2009 +0100
replace stat("/etc/disable-guest-log-throttle") in xen_platform.c
currently xen_platform reads /etc/disable-guest-log-throttle at boot to
decide whether is going to throttle guest logging or not.
When using stubdom this is the only code in qemu that rely on
fs-backend, apart from saving and loading the statefile for migration.
This patch removes the read from /etc and adds a read from xenstore
instead.
