Lustre discuss - Oct 2010 - class_handle_ioctl function looks not safe

Hi list,


class_handle_ioctl (which used for lctl and other tools) looks not safe, because
it uses class_num2obd and class_name2obd
which don''t get extra reference for obd device, so that device can
destroyed when some tool work with it.
