They can move mapping if the locking is right and the helpers handle it because you can invalidate the pages in the userspace mappings and they will get faulted back with the new ones. > Because I'm not 100% sure nothing will get written to it, and if Fair point. > something gets written > to it I'd rather not have to complicate the oops printing to have to > page in memory > from disk, when it might be the disk that caused the oops. If the box was horked that way then you are going to fail to migrate the graphical frame buffer out in order to go into text mode to print the oops. Probably safest any oops hits the current visible object ?
