Runtime repartitioning

Runtime repartitioning

[Tim Cussins]

Hi all,

In July 2010 a couple of competing patchsets were submitted that aimed 
to provide runtime repartitioning of mtd devices.

http://thread.gmane.org/gmane.linux.drivers.mtd/30458
http://thread.gmane.org/gmane.linux.drivers.mtd/30950
http://thread.gmane.org/gmane.linux.drivers.mtd/30949

Neither submission was accepted, comments were given on and off list, 
and that was the end of it :)

The ability to create new mtd partitions after boot would be awesome - 
how can I get involved in getting such functionality into the tree?

Cheers,
Tim

It's probably a good idea to at least CC those who worked on this
before...I added Roman Tereshonkov, the one who started the
discussion.

Anyway, it looks like Roman ended up submitting a revised version of
the patch from the first discussion. His work made it into the kernel
as the following two commits. You can feel free to test it yourself!

Hi Brian,

Whoa, they've been in for a while... I was looking in mtd-api.h for ioctls

Thanks heaps,
