Babu, Compiling with "make W=1" you have several kerneldoc comments on new functions that do not describe their parameters. E.g. /** * resctrl_config_cntr() - Configure the counter ID for the event, RMID pair in * the domain. * * Assign the counter if @assign is true else unassign the counter. Reset the * associated non-architectural state. */ static void resctrl_config_cntr(struct rdt_resource *r, struct rdt_mon_domain *d, enum resctrl_event_id evtid, u32 rmid, u32 closid, u32 cntr_id, bool assign) Warning: fs/resctrl/monitor.c:984 function parameter 'r' not described in 'resctrl_config_cntr' Warning: fs/resctrl/monitor.c:984 function parameter 'd' not described in 'resctrl_config_cntr' Warning: fs/resctrl/monitor.c:984 function parameter 'evtid' not described in 'resctrl_config_cntr' Warning: fs/resctrl/monitor.c:984 function parameter 'rmid' not described in 'resctrl_config_cntr' Warning: fs/resctrl/monitor.c:984 function parameter 'closid' not described in 'resctrl_config_cntr' Warning: fs/resctrl/monitor.c:984 function parameter 'cntr_id' not described in 'resctrl_config_cntr' Warning: fs/resctrl/monitor.c:984 function parameter 'assign' not described in 'resctrl_config_cntr' -Tony
