[PATCH 0/2][t/u/v/w/x/y SRU] Fix oops during mount propagation

[Seth Forshee]

BugLink: http://bugs.launchpad.net/bugs/1572316

These upstream cherry picks fix an oops during mount propagation for
certain mount tree configurations. Actually only the second fixes the
oops; the first is a prerequisite that I could have backported around,
but it's a worthy fix on its own so I opted to include it. Yakkity will
only need the second patch.

Thanks,
Seth
