It only works with ram/rom, and we use it in a virtual environment to share data between multiple virtual machines. After a long discussion with Joern Engel and David Woodhouse, I believe we came up with an idea how we would extend the existing xip support to work with memory technology device.

And s390 is the only exploiter of xip to date. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
