Yes. Thank you for pointing out this, we'd better add Cc: stable tag.
But we have to backport the patch for -stable trees because the code base
is changed by following upstream commits:
(1) For all stable trees: in commit abe8f12b4425 ("x86/resctrl: Remove
unused struct mbm_state::chunks_bw"), removing unused struct
mbm_state::chunks_bw changes the code base for this patch.
(2) For 4.14 and 4.19 stable trees: in commit fa7d949337cc ("x86/resctrl:
Rename and move rdt files to a separate directory"), the file
arch/x86/kernel/cpu/intel_rdt_monitor.c has been renamed and moved to
arch/x86/kernel/cpu/resctrl/monitor.c. This patch needs to be rebased.
I plan to do backporting for all -stable trees after this patch is merged
into upstream.
Thank you.
