[Popcornlinux-devel] where is the code about "runtime repartitioning" ?

[Yuwang (C) <yuw...@hu...>]

I works at huawei company， we will plan to use popcronlinux, but I have some questions about it.

From http://www.popcornlinux.org/， it write that:
 Hardware resources (i.e., disks, network interface cards) are partitioned per kernel instance, and runtime repartitioning allows any kernel to have exclusive access to any device.

Questions:
1, Is it means that device disk A partitioned kernel A, but kernel B also can access device disk A? how to achieve it ? by kernel A sharing some data message to kernel B , or repartitioning(after
repartitioning to kernel B, is that kernel A can’t access device disk A, right? )
2, I can’t found the commit code or patch from http://www.popcornlinux.org/sources/x86_64/linux-3.2.14-popcorn-march2013.patch and git log, coud anyone help me, tell me
    the git commit number about it.
