[patch 22/60] CIFS: mount of IPC$ breaks with iget patch

[Greg KH]

2.6.26-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Steve French <sfrench@xxxxxxxxxx>

commit ad661334b8ae421154b121ee6ad3b56807adbf11 upstream

In looking at network named pipe support on cifs, I noticed that
Dave Howell's iget patch:

    iget: stop CIFS from using iget() and read_inode()

broke mounts to IPC$ (the interprocess communication share), and don't
handle the error case (when getting info on the root inode fails).

Thanks to Gunter who noted a typo in a debug line in the original
version of this patch.
