linux-toradex.git/fs/pnode.h, branch v3.9-rc3 Linux kernel for Apalis and Colibri modules vfs: Only support slave subtrees across different user namespaces 2012-11-19T13:59:20+00:00 Eric W.

Sharing mount subtress with mount namespaces created by unprivileged
users allows unprivileged mounts created by unprivileged users to
propagate to mount namespaces controlled by privileged users.

Prevent nasty consequences by changing shared subtrees to slave
subtress when an unprivileged users creates a new mount namespace.
