From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
4.9.115-rt94-rc1 stable review patch. If you have any objection to the inclusion of this patch, let me know.
--- 8< --- 8< --- 8< --- Under certain circumstances we could leak elements which were moved to the local "to_free" list. The damage is limited since I can't find any users here.
