Provide a way to check and modify them. > Why? If a vm's max_halt_poll_ns has been set using KVM_CAP_HALT_POLL, the module parameter kvm.halt_poll.ns will no longer indicate the maximum halt pooling interval for that vm. After introducing these two attributes into debugfs, it can be used to check whether the individual configuration of the vm is enabled and the working value. This patch provides a way to check and modify them through the debugfs.
