22 object, it may make more sense to create a new filesystem or device. This
23 also makes it easier to encapsulate the new functionality in a kernel module
26 - If the new functionality involves operations where the kernel notifies
27 userspace that something has happened, then returning a new file
35 - If you're just exposing runtime system information, a new node in sysfs
44 this option is best for when the new function is closely analogous to
