[Qemu-devel] [PULL 2.7 3/4] migration: fix live migration failure with compression |

From: Liang Li <address@hidden>
Because of commit 11808bb0c422, which remove some condition checks
of 'f->ops->writev_buffer', 'qemu_put_qemu_file' should be enhanced
to clear the 'f_src->iovcnt', or 'f_src->iovcnt' may exceed the
MAX_IOV_SIZE which will break live migration. This should be fixed.
