[patch 05/21] fs/inode.c: add dev-id and inode number for debugging in init_special_inode()

[akpm@linux-foundation.org]

From: Manish Katiyar <mkatiyar@gmail.com>

Add device-id and inode number for better debugging.  This was suggested
by Andreas in one of the threads
http://article.gmane.org/gmane.comp.file-systems.ext4/12062 .

"If anyone has a chance, fixing this error message to be not-useless would
be good...  Including the device name and the inode number would help
track down the source of the problem."
