Al Viro 4edbe133f8 make struct mountpoint bear the dentry reference to mountpoint, not struct mount
Using dput_to_list() to shift the contributing reference from ->mnt_mountpoint
to ->mnt_mp->m_dentry.  Dentries are dropped (with dput_to_list()) as soon
as struct mountpoint is destroyed; in cases where we are under namespace_sem
we use the global list, shrinking it in namespace_unlock().  In case of
detaching stuck MNT_LOCKed children at final mntput_no_expire() we use a local
list and shrink it ourselves.  ->mnt_ex_mountpoint crap is gone.
