    Subject[28/90] ext4: Always set dx_nodes fake_dirent explicitly.
    2.6.31-stable review patch.  If anyone has any objections, please let us know.

    ------------------
    (cherry picked from commit 1f7bebb9e911d870fa8f997ddff838e82b5715ea)

    When ext4_dx_add_entry() has to split an index node, it has to ensure that
    name_len of dx_node's fake_dirent is also zero, because otherwise e2fsck
    won't recognise it as an intermediate htree node and consider the htree to
    be corrupted.
