Subject: [PATCH V3 0/5] Add MMC erase and secure erase V3

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 3 of these patches.

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
