Hi Marcelo,

there isn't fixed the d_path() long name truncation vulnerability
(see http://cert.uni-stuttgart.de/archive/bugtraq/2002/03/msg00384.html) in
2.4.x up to 2.4.21-BK.

This trivial patch fixes it. Instead of truncating the path with no error, 
caller gets ENAMETOOLONG.

Patch credits go to Jirka Kosina.

Has been in WOLK and in -aa kernels for ages.

ciao, Marc
