With this trivial helper, we could get a little benefit to simplify
the code logic of xfs

There a silent agreement on this probably "since beginning" already
(cf. [1]). Enforce it to move a boundary of what it explicitly wrong
a bit futher.
Counterpart changeset for fence-agents (relevant branch) will follow.
