Currently nfsd_mountpoint() tests for mount points using d_mountpoint(), this works only when a mount point is already uncovered. In our case the mount point is of type auto mount and can be coverted. i.e. ->d_automount() was not called. Using d_managed() nfsd_mountpoint() can test whether a mount point is either already uncovered or can be uncovered later.
