Thanks a lot for the tip. lookup_dentry() works fine. I'm trying to
develop a filesystem which will involve mounting a directory tree at a
mount point (don't ask me why, I don't know myself!) so I need to get a
handle on its inode. The constant pathname is just there to simplify
coding at an early stage. Eventually, I'll be taking the pathname as a
parameter.
