Since commit 041ee6f3727a ("kthread: Rely on HK_TYPE_DOMAIN for preferred
affinity management"), the HK_TYPE_KTHREAD housekeeping cpumask may no
longer be correct in showing the actual CPU affinity of kthreads that
have no predefined CPU affinity. As the ipvs networking code is still
using HK_TYPE_KTHREAD, we need to make HK_TYPE_KTHREAD reflect the
reality.This patch series makes HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN and uses RCU to protect access to the HK_TYPE_KTHREAD housekeeping cpumask.
