Did the cifs version change?

I wonder if one of the entries in the buffer hit the known cifs_readdir 
bug in which the filename is converted from Unicode to UTF-8 in place 
(which can result in overrunning into the next entry in the buffer for 
certain Asian languages in particulr)

That is not strange - lookup is going to work no matter what readdir 
returns if the file/dir really exists - and even the caching of inode 
metadata information returned from readdir or lookup is only kept for a 
short time.

Would not mind seeing an ethereal trace of the failing SMB 
FindFirst/FindNext frames but it also might be good enough to turn on 
debugging "echo 1 > /proc/fs/cifs/cifsFYI" and send or post the dmesg 
output from the readdir processing
