mmc: fix compilation of user API

2020-06-11T07:22:20Z

commit 83fc5dd57f86c3ec7d6d22565a6ff6c948853b64 upstream. The definitions of MMC_IOC_CMD and of MMC_IOC_MULTI_CMD rely on MMC_BLOCK_MAJOR: #define MMC_IOC_CMD _IOWR(MMC_BLOCK_MAJOR, 0, struct mmc_ioc_cmd) #define MMC_IOC_MULTI_CMD _IOWR(MMC_BLOCK_MAJOR, 1, struct mmc_ioc_multi_cmd) However, MMC_BLOCK_MAJOR is defined in linux/major.h and linux/mmc/ioctl.h did not include it.

mmc: block: Add new ioctl to send multi commands

2015-10-26T15:00:00Z

Certain eMMC devices allow vendor specific device information to be read via a sequence of vendor commands. These vendor commands must be issued in sequence and an atomic fashion. One way to support this would be to add an ioctl function for sending a sequence of commands to the device atomically as proposed here. These multi commands are simple array of the existing mmc_ioc_cmd structure. The structure passed via the ioctl uses a __u64 type to specify the number of commands (so that the structure is aligned on a 64-bit boundary) and a zero length array as a header for list of commands to be issued. The maximum number of commands that can be sent is determined by MMC_IOC_MAX_CMDS (which defaults to 255 and should be more than sufficient). This based upon work by Seshagiri Holi .
