First read again. fstat doesnt report a name, it reports the inode
*number*.

The point is looking up the path/filename for this inode *fast*, got it? :)

lsof can do so:
# lsof -p `cat /var/run/syslog.pid`

Please note that lsof uses the namei cache of the kernel here, which speeds
up the lookup. (see -C for a different output)
Of course this has "problems", since it's not guaranteed the file/inode
would be in the namei cache.. *shrug* after all, it's not an easy task :)
