Title:
oops when propagating mounts
** Description changed:
+ SRU Justification:
+
+ Impact: Propagation to some mount tree configurations can cause the
+ kernel to oops. This is trivially reproducible using lxd.
+
+ Fix: Cherry pick from upstream user-namespace.git tree. Pull request
+ into Linus' tree is pending.
+
+
Fix sent to Linus:
http://lkml.kernel.org/r/87zis4wna1.fsf...@x220.int.ebiederm.org
I've tested this on xenial and it fixes the oops. I'll send out patches
shortly.

Hi, I'm having a kernel oops with similar trace, but for me it happens at login
time. Maybe there's an automatic mount.

This doesn't have to be an nfs mount, I've been able to reproduce it
using an ext4 loopback mount.
