Subject: [PATCH 03/16] migration: Use qemu_file_transferred_noflush() for block migration.
Date: Tue, 30 May 2023 14:28:00 +0200	[thread overview]
Message-ID: <20230530122813.2674-4-quintela@redhat.com> (raw)
In-Reply-To: <20230530122813.2674-1-quintela@redhat.com>

We only care about the amount of bytes transferred.  Flushing is done
by the system somewhere else.
