RE: Getting full pathname for dentry

["Gerd M" <gerd_m1977@hotmail.com>]

Meanwhile i came to the conclusion that i can't use user_path_walk and 
therefore have to use d_path like this:

pathname = d_path( dentry, current->fs->rootmnt, buffer, namelen );

Unfortunately this doesn't get across mount points, meaning if /usr is a 
mountpoint then touch /usr/test gives "/test" as the full pathname.

Any hints are welcome!
