Subject: RE: [rfc] suppress excessive AER output

Dave,

My idea is application has opportunity to reset it. Consider the critical mission environment, admin could hot-unplug any failed devices without rebooting system. Then, admin doesn't want to lose AER monitoring.

With the module parameter, admin could change it under /sys/module/aer_drv/parameters.

Sure. Though for the built-in case, how would that work ?
