Meta-GGA calculations require POTCAR files that include information on the kinetic energy density of the core-electrons. To check whether a particular POTCAR contains this information, type:

grep kinetic POTCAR
This should yield at least the following lines (for each element on the file):

kinetic energy-density
mkinetic energy-density pseudized
and for PAW datasets with partial core corrections:

kinetic energy density (partial)
