[Cluster-devel] [PATCH 2/2] [GFS2] re-support special inode

[Denis Cheng <crquan@gmail.com>]

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.
