Hi everyone,
This patch aims to enable purecap applications to make use of the MMC block driver by adding PCuABI support to the MMC_IOC_CMD and MMC_IOC_MULTI_CMD ioctls. This also includes compat64 support for the ioctls.
V6 -> V7: Clarify comments on ioctl numbering.
V5 -> V6: Fix for ioctl numbering based on struct size; minor corrections.
V4 -> V5: Improvement to readability and fix to user-space macro.
V3 -> V4: Minor corrections and improvements to readability of code. - Remove unnecessary explicit checks on capabilities. - Revert modification to struct mmc_ioc_multi_cmd. - Remove unnecessary parentheses.
V2 -> V3: - Implement support for capabilities in the ioctls. - Correct formatting errors in patches. - Correct formatting and syntax errors in code.
V1 -> V2: Various improvements to the code including: - Preference for native structs over (void __user *) - Complying with code styling guidelines - Improvement in code readability via removing unnecessary casts
