Hi , I am planning to use the existing IOCTL interface for SD/MMC present in the kernel. Since, the IOCTL interface expects a read/write flag , and the MMC IOCTL is actually an interface to block layer I feel without modifying the block layer for the support of non-read write commands ,I may not be able to test the non-read/write commands through the IOCTL interface . Is there a way of doing this without modifying block layer ? -- regards, Shashidhar Hiremath -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
