Hi Vivek, We can make description file with tunable_notifier_chain_register 4th argument. If developer sets 4th argument, tunable_notifier_chain_register makes /sys/kernel/debug/<name>/description file. Admin can get information from the description file. +/** + * tunable_notifier_chain_register - Add notifier to an tunable notifier chain + * @nh: Pointer to head of the tunable notifier chain + * @n: New entry in notifier chain + * @name: Pointer to the name of the new notifier entry + * @desc: Pointer to the description of new entry + * + * Adds a notifier to an tunable notifier chain and makes control dir. + * + * Returns zero on success or %-ENODEV on failure. + */ Thanks, Takenori Nagano <t-nagano at ah.jp.nec.com>
