| H A D | namespace.c | d71ed6c9 Fri May 27 14:50:05 CDT 2016 Eric W. Biederman <ebiederm@xmission.com> mnt: fs_fully_visible test the proper mount for MNT_LOCKED
MNT_LOCKED implies on a child mount implies the child is locked to the
parent. So while looping through the children the children should be
tested (not their parent).
Typically an unshare of a mount namespace locks all mounts together
making both the parent and the slave as locked but there are a few
corner cases where other things work.
