Hi, all:
I am reading the implementation of shared-subtree in linux kernel. There are two limits about move operation confused me badly, I have read the design document -- Shared-Subtree Concept, Implementation, and
Applications in Linux ,but still puzzled.
1.Why can't move a mount residing in a shared mounts?
2.Why can't move a mount tree containing an unbindable mount to a shared mount?Is it not a good way to prune out unbindable mounts just like rbind semantics do?
Thanks in advance
Rock Lee
