    Subject[PATCH 38/48] [GFS2] re-support special inode
    Date
    From: Denis Cheng <crquan@gmail.com>

    a previous commit removed call to
    init_special_inode from inode lookuping, this cause problems as:

    # mknod /mnt/gfs2/dev/null c 1 3
    # cat /mnt/gfs2/dev/null
    cat: /mnt/gfs2/dev/null: Invalid argument

    without special inode, GFS2 cannot support char device file,
    block device file, fifo pipe, and socket file, lose many important
    features as a common file system.

    this one line patch re add special inode support.
