Subject[PATCH v2 0/3] x86/intel_rdt: task_work vs task_struct rmid/closid write race
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.


v1 -> v2
Empty git diff between the two, but:

o Collected Reviewed-by
o Reworded changelogs (James)
o Split READ_ONCE/WRITE_ONCE changes into separate patch (James)
(@James: note that I had the audacity to slap your RB to that new patch,
given that you already reviewed the diff. Hopefully you won't hate the
CL too much!)


Valentin Schneider (3):
x86/intel_rdt: Check monitor group vs control group membership earlier
x86/intel_rdt: Plug task_work vs task_struct {rmid,closid} update race
x86/intel_rdt: Apply READ_ONCE/WRITE_ONCE to task_struct .rmid &
