Steve,

I think I will have to apply similar logic in cifs_lookup for lookup
intents i.e. when
cifs_posix_open fails with the same return code, follow the usual lookup path, I
do not have to disable posix opens though as Simo said.
Would be wasting a transaction in the process though in case of samba servers
that have this problem.

Regards,

Shirish
