> Dear all,
> So here is a new version of the patches to be reviewed, this time as
> suggested by Alasdair the patches are reworked to match with the new
> dmsetup bootformat feature . These patches are not reviewed yet but
> the format was discussed in the IRC and was suggested to send the
> kernel patches in parallel.
> Changes since v6:
> - Add a new function to issue the equivalent of a DM ioctl programatically.
> - Use the new ioctl interface to create the devices.
> - Use a comma-delimited and semi-colon delimited dmsetup-like commands.
> Changes since v5:
> - https://www.redhat.com/archives/dm-devel/2016-February/msg00112.html
>  https://www.redhat.com/archives/linux-lvm/2017-May/msg00047.html
> Wating for your feedback,
> Enric Balletbo i Serra (1):
> dm ioctl: add a device mapper ioctl function.
> Will Drewry (1):
> init: add support to directly boot to a mapped device
