>I haven't been using kernel v4.1 so I haven't seen this warning, but looking >at the code it seems to originate from the two recent patches to remove >_cancel_timer and _cancel_timer_ex. I see that there's another patch in lkml [1] >that changes del_timer_sync back to del_timer in more places. Perhaps it >could prevent other warnings like this in the future. _cancel_timer and _cancel_timer_ex both were internally using del_timer, and the issue was reported in bugzilla. I have given the reference of the bugzilla in my patch in lkml. I have changed the reference of del_timer_sync to del_timer in all places which were in interrupt context, in some places it was not removed as those were not in interrupt context. regards sudip -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
