mm_struct is the central object for a heavyweight process.  All threads
within that process share the same executable path (don't they?) so
attaching the executable path to the mm seems OK to me.

What I always find a bit weird is that an MM container is used as the
central point for a number of sched obects.  But it's logical, given
that the never-before-stated definition of a heavyweight process is
"thing which share a VM".
