The 21-year-old has had a stop-start season and has found himself mainly on the substitutes' bench since the turn of the year.
Leeds signed Warnock in January and the former England international has made White's favourite left-back position his own.
"It's frustrating obviously," Republic of Ireland Under-21s international White said.
"I was playing nearly every game last season and this time I've been in and out and on the bench for most of it.
"So it's very frustrating, but I've got to look on the positive side of things.
"Stephen Warnock has come in and he's a fantastic player.
"I look at him and try and learn from him because he's an ex-England international.
"I've already picked up a few pointers off him so when I do get back in the team, hopefully sooner rather than later, I'll improve myself as a player.
"Especially as he's in the same position as me, as frustrating as it is not playing, I do like to look on the positive side of things and if I can learn off Stephen and improve then I will."
