      Description

      Lustre has the ability to tune proc values using lctl conf_param on the MGS server. Those changes are stored and distributed to all the nodes avoiding to the complex process of setting ever node. The function class_process_proc_param() is used to change the setting using the lprocfs_vars that map to the proc file. With the move to sysfs/debugfs this no longer works. A new approach has to be written to handle sysfs settings. Also we should consider dropping setting debugfs entries since they tend to contain large quantities which the user will typical not set that kind of data
