commit feaa7bba026c181ce071d5a4884f7f9dd26207a1 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.

Hi,
Both patches are now in the -nmw git tree. Sorry for the delay. I've
changed the comment on the second one since that commit ID didn't appear
to match up with the right patch.
Steve.
