Freebsd namei equivalent in Linux VFS

[naresh kumar]

Folks,

Is there any equivalent of this namei(9) freebsd thingy in linux ? Here is the 
man page for the freebsd namei filters say 
http://www.freebsd.org/cgi/man.cgi?query=namei&sektion=9

Any pointers for this in linux are appreciated.

Thanks
Naresh.
