Summary
fs/resctrl: Fix double-add of pseudo-locked region's RMID to free list
Details

In the Linux kernel, the following vulnerability has been resolved:

fs/resctrl: Fix double-add of pseudo-locked region's RMID to free list

A pseudo-locked group's RMID is freed when it is created. On unmount rmdirallsub() unconditionally frees all RMID of all groups, resulting in a double-free of the pseudo-locked group's RMID. The consequence of this is that the original free results in the pseudo-locked group's RMID being added to the rmidfreelru linked list and the second free then attempts to add the same RMID entry to the rmidfreelru again.

Do not double-free a pseudo-locked group's RMID.
