Keeping it mapped to=0D HK_TYPE_KERNEL_NOISE is no longer accurate, so the alias is the right fix.= =0D =0D Patch 2 properly introduces RCU protection for accessing the=0D HK_TYPE_KTHREAD/HK_TYPE_DOMAIN cpumask in IPVS. Since the mask can now=0D change at runtime, guarding against potential UAF is required. The=0D changes are minimal and the helper wrappers keep call sites clean.=0D =0D Reviewed-by: David Dull =
