[patch 22/94] minix: fix add links wrong position calculation

[Greg KH]

2.6.28-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Evgeniy Dushistov <dushistov@xxxxxxx>

commit d6b54841f4ddd836c886d1e6ac381cf309ee98a3 upstream.

Fix the add link method.  The oosition in the directory was calculated in
wrong way - it had the incorrect shift direction.
