[Qemu-devel] [PATCH 0/4] linux-user: kpartx fixes

[Alexander Graf <agraf@suse.de>]

As part of our OBS build process, we also want to be able to create kiwi images
for ARM on x86 hardware. One of the crucial bits there is the kpartx tool, since
that allows us to map images on the fly through device mapper.

So this patch set goes in and implements all the device mapper ioctls and fixes
a few hickups to actually make things work along the way. With this applied, I
can successfully run kpartx -av on an image file and have that available in the
system. As far as possible, I also verified all the other ioctls to actually
work.
