Loic/Linus/Chris, I think the IOCTL is not complete in terms of handling
the RPMB requests. Here is why I think that is - let me know your
opinion
There are four request types that are needed to be supported - two under

Yes exactly, you have to first

I've merged this to mmc-next for 3.8 now; thanks to everyone who Acked.
If you have any userspace sample code that could be added to mmc-utils
to show how the interface can be used, feel free
Hi,
Any specific reason why the RPMB support is implemented using the
IOCTL interface. Can this be done by the Kernel itself instead of
being initiated by a user space application ?

Hi,
There are several reasons for that:
- RPMB partition supports
as defined by JEDEC standard.

Changes in v2:
- Correction in patch 2: mmc: card: Do not scan RPMB partitions
Remove GENHD_FL_EXT_DEVT flag
Changes in v3:
- Add acked-by and reviewed-by tags

Loic Pallardy (5):
mmc: core: Expose access to RPMB partition
mmc: card: Do not scan RPMB
Following JEDEC standard, if the mmc support RPMB partition,
a new interface is created and exposed via /dev/block.
Users will be able to access RPMB partition using standard
mmc IOCTL command.

Should it wrapped by if (is_rpbm) condition ? It can be called in other

It was my first implementation, but in that
