Cover letter [PATCH V4 0/5] Add MMC erase and secure erase V4
Hi
Add ability to do MMC erase and secure erase operations from userspace, using the BLKDISCARD ioctl and a newly created BLKSECDISCARD ioctl.
This is version 4 of these patches.
Changes from V3
- rebased on mmotm
- added SD/MMC device attribute documentation to 'mmc: Add erase, secure erase, trim and secure trim operations' patch
Changes from V2
- move the addition of BLKSECDISCARD to a separate patch and implement it using I/O requests
- move the MMC support of secure discard to a separate patch and support the secure discard I/O request
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
