  Few comments upon Ali and Khalil's paper are pointed out. Their modified
Schwarzschild metric seems not to be new as it has the same structure as Eq.
(2.6) from Ref.4. Their black hole temperature $T$ and heat capacity $C$
correspond exactly to the Reissner-Nordtstrom values, with $\hbar \eta$ instead
of $Q^{2}$. The expression for the black hole entropy turns out to be erronous
and does not fit with the other authors' calculations. Moreover, a lot of
equations have wrong physical units (terms in the same equation have different
units).
