This patchset has gone through a few iterations. v1 is based on a different concept, where a separate partition is used as a master, and partitioning is simply made more flexible. v2 switched to the model of the master coexisting with the partitions. v3 brings back the patch to remove overlap checks, as testing discovered that the overlap checks were buggy. This version also makes some style improvements. v4 fixes some style issues in the sysfs patch and adds documentation.
