I fully agree. Also please make that user limit settable use module_param too,
not only sysfs. I recently had the pleasure to deal with a failing disk
which started to spew errors already on device probing and it somewhat
annoyed me that that slowed down boot up time that much. Perhaps the default
during device probing should be also lower?
