From 8996604fe6b9e6646883f70e737b9440e7563c87 Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Wed, 10 Jul 2019 13:08:14 +0800 Subject: migration/postcopy: do_fixup is true when host_offset is non-zero This means it is not necessary to spare an extra variable to hold this condition. Use host_offset directly is fine.
