"debugfs_create_file(...fops)" has take "fops" as its argument. I guess that this can deal with the above. For "set_parent", would it be possible to do that by using "debugfs_rename()"? And if there will be a little possibility that sysfs attribute can be used by userland in the future, keeping sysfs instead of debugfs doesn't seem not so illegal, does it?
