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.
Revisions
=========
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!)
Cheers,
Valentin

x86/intel_rdt: Apply READ_ONCE/WRITE_ONCE to task_struct .rmid &
.closid
