Only nitpicks are: - ps3disk_priv should probably be an inline function instead of a macro - ps3disk_open is not needed at all and should be removed completely. - please remove PS3DISK_MAJOR - and just pass 0 to register_blkdev. Passing 0 to get an unassigned dev_t range is the normal convention and giving it a suprising symbolic names makes reading the code a little harder. - put_disk in ps3disk_remove should be done after you finished tearing down the device, not before - calling free_irq directly followed by request_irq in ps3disk_probe looks rather dumb. I'd rather move the request_irq out of ps3stor_setup into the low-level driver. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
