Hi all, I have a question for mmc_blk_ioctl_cmd. I did not see any sync code in this function like mutex, semphere.., why? The ioctl will do partition switch as I know, so If more partitions call the ioctl from user layer at the same time, how to sync with them? -- Wan ZongShun. www.mcuos.com -- 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
