Hmm... the best way would be implementing an EH action for PMP r/w and export it via ioctl or sysfs.

That would automatically solve synchronization problem too. -- tejun -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
