Subject: [Qemu-devel] [PATCH 1.2 2/7] savevm: flush after saving vm state
Date: Tue, 22 May 2012 18:17:13 +0200	[thread overview]
Message-ID: <1337703438-9764-3-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1337703438-9764-1-git-send-email-pbonzini@redhat.com>

Writing vm state uses bdrv_pwrite, so it will automatically get flushes
in writethrough mode.  But doing a flush at the end in writeback mode
is probably a good idea anyway.
