Let $G$ be a finite group and
$H$,
$K$ two subgroups of
$G$. A group
$G$ is said to be a mutually
$m$-permutable product of
$H$ and
$K$ if
$G\,=\,HK$ and every maximal subgroup of
$H$ permutes with
$K$ and every maximal subgroup of
$K$ permutes with
$H$. In this paper, we investigate the structure of a finite group that is a mutually
$m$-permutable product of two subgroups under the assumption that its maximal subgroups are totally smooth.
