3.4.107-rc1 review patch. If anyone has any objections, please let me know.
------------------
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.
