Commit 820f9f147dcce2602eefd9b575bbbd9ea14f0953 (fs_pin: Allow for the possibility that m_list or s_list go unused) in main kernel tree fixes kernel crash. I encountered this crash when ran test on libcontainer project. Seems like some problem with mounts under nested user-namespaces. It was introduced in 4.0.2.
