Ah, indeed it is. I was thinking of the way I had written my patch, where it only does the spindown if the system state is SYSTEM_POWER_OFF so I needed an extra call to force this on removal. Tejun's patch just checks for not SYSTEM_RESTART, so it should happen on removal as well. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@...pamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
