From: Dave Kleikamp <dave.kleikamp@oracle.com>

Upstream commit 44512449, "jfs: fix readdir cookie incompatibility
with NFSv4", was backported incorrectly into the stable trees which
used the filldir callback (rather than dir_emit). The position is
being incorrectly passed to filldir for the . and .. entries.

The still-maintained stable trees that need to be fixed are 3.2.y,
3.4.y and 3.10.y.
