The equation is wrong because it specifies mass, m, as *the* mass,
i.e. the definitive mass or the one-and-only mass.

Correctly written, the *inertial* mass must be indicated because,
as already stated, there are two different "kinds" of mass.

For some reason, the concepts of inertial mass and gravitational
mass have been effectively purged from physics, but they are still
valid.  GR *assumes* the equivalence of both types and perhaps for
this reason all textbooks incorrectly mention only a single type
of mass.  But, as also mentioned, GR is not yet universally established.
