[PATCH V2 0/4] Add MMC erase and secure erase

[Adrian Hunter]

Hi

Add ability to do MMC erase and secure erase operations from userspace,
using the BLKDISCARD ioctl and a newly created BLKSECDISCARD ioctl.

Changes from V1

- use discard I/O requests instead of implementing BLKDISCARD in mmc_block
- do not validate erase size for MMC erases, instead round to erase size
- rename MMC max_erase to pref_erase and expose it through sysfs as
"preferred_erase_size"

Adrian Hunter (4):
     block: Add BLKSECDISCARD
     mmc: Add erase, secure erase, trim and secure trim operations
     mmc_block: Add discard and secure discard support
     omap_hsmmc: Add erase capability
