TYPO3 Core

I have a PHP error because of bad use of the function closedir() > http://php.net/closedir

The argument chould be a handler and not the path of the dir itself.

It's triggered in the brand new "internal_clearPageCache()" function.

It can be corrected by changing
6222 : closedir($cacheDir);
into
6222 : closedir($topDir);

$topDir is the handler from @opendir($cacheDir) on line 6208
