commit b8511ccc75c033f6d54188ea4df7bf1e85778740 upstream.
A resource group (rdtgrp) contains a reference count (rdtgrp->waitcount) that indicates how many waiters expect this rdtgrp to exist. Waiters could be waiting on rdtgroup_mutex or some work sitting on a task's workqueue for when the task returns from kernel mode or exits.
I've queued up the 4.19 and 4.14 backports, thanks!
