    ovl: don't traverse automount points · a6f15d9a
    Miklos Szeredi 提交于
    NFS and other distributed filesystems may place automount points in the
    tree.  Previoulsy overlayfs refused to mount such filesystems types (based
    on the existence of the .d_automount callback), even if the actual export
    didn't have any automount points.
    
    It cannot be determined in advance whether the filesystem has automount
    points or not.  The solution is to allow fs with .d_automount but refuse to
    traverse any automount points encountered.
