[PATCH 0/2] x86/intel_rdt: task_work vs task_struct rmid/closid write race

[Valentin Schneider]

Hi folks,

This is a small cleanup + a fix for a race I stumbled upon while staring at
resctrl stuff.

Briefly tested on a Xeon Gold 5120 (m2.xlarge.x86 on Equinix) by bouncing a few
tasks around control groups.

Cheers,
Valentin
