This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This directory doesn't use the special "create proc mountpoint" interface and thus fails the permanently empty test in fs_fully_visible(). This causes mounting of proc to fail in user namespace containers. Fix: Use the special proc interface to make this a "permanently empty" directory. Regression potential: This change will make it impossible to create files within /proc/xen, but since the directory is only ever used as a mount point this should not cause any problems.
