Shawn Lin 83c742c344 mmc: block: fix ABI regression of mmc_blk_ioctl ... If mmc_blk_ioctl returns -EINVAL, blkdev_ioctl continues to work without returning err to user-space. But now we check CAP_SYS_RAWIO firstly, so we return -EPERM to blkdev_ioctl, which make blkdev_ioctl return -EPERM to user-space directly. So this will break all the ioctl with BLKROSET. Now we find Android-adb suffer it for the following log: remount of /system failed; couldn't make block device writable: Operation not permitted openat(AT_FDCWD, "/dev/block/platform/ff420000.dwmmc/by-name/system", O_RDONLY) = 3 ioctl(3, BLKROSET, 0) = -1 EPERM (Operation not permitted) Fixes: a5f5774c55 ("mmc: block: Add new ioctl to send multi commands") Cc: stable@vger.kernel.org Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>		2016-03-17 14:54:42 +01:00
