The commit 89f7ca1af15bdfe7a6aed343032a84af2a69f736 makes next-20140818 to panic because mountpoint list head was not initialized. Initializing it with NULL fixes the problem.

vfs: Keep a list of mounts on a mount point
To spot any possible problems call BUG if a mountpoint is put when it's list of mounts is not empty.
AV: use hlist instead of list_head
