  The classical Raychaudhuri equation predicts the formation of conjugate
points for a congruence of geodesics, in a finite proper time. This in
conjunction with the Hawking-Penrose singularity theorems predicts the
incompleteness of geodesics and thereby the singular nature of practically all
spacetimes. We compute the generic corrections to the Raychaudhuri equation in
the interior of a Schwarzschild black hole, arising from modifications to the
algebra inspired by the generalized uncertainty principle (GUP) theories. Then
we study four specific models of GUP, compute their effective dynamics as well
as their expansion and its rate of change using the Raychaudhuri equation. We
show that the modification from GUP in two of these models, where such
modifications are dependent of the configuration variables, lead to finite
Kretchmann scalar, expansion and its rate, hence implying the resolution of the
singularity. However, the other two models for which the modifications depend
on the momenta still retain their singularities even in the effective regime.
