Latin -u/o/i-lentus < *PIE - went-?

What's the PIE analysis of Latin suffix -ulentus "full of"? It seems to be
related to PIE -went-/-wnt- suffix, but how about the -l? A crossignf with
L-adjectives like similis, facilis, pestilis, credulus ?
corpulentus
flatulentus
opulentus
virulentus
violentus
somnolentus
feculentus
pu:rulentus
sanguinolentus
esculentus
fraudulentus
truculentus
pestilentus
but
cruentus

A link to L-suffix in verbs like postulare, ustulare?
