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 v7: - Fix build error due commit e516db4f67 (dm ioctl: add a new DM_DEV_ARM_POLL ioctl) 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.
