Subject: [PATCH 0/2] sched: rseq mm_cid updates

Hi,

This patch series consists of 2 patches. It is based on v6.9-rc4.

- A fix aiming for v6.9-rc (to be backported to stable kernels):
  "sched: Add missing memory barrier in switch_mm_cid"

- An improvement patch aiming for v6.10:
  "sched: Move mm_cid code from sched.h to core.c"

Thanks,

Mathieu
