So in this case exporting any new sysfs file (or using existing) which report POLLPRI events for LED devices with active trigger is not accepted. This means that trigger itself is problematic and trigger code should tell to led subsystem if it should send POLLPRI events to userspace or not. E.g. cpu trigger should tell led subsystem that events must not be sent and e.g. rfkill trigger could tell that events can be sent... -- Pali Rohár pali.ro...@gmail.com
