From e670b3564c3c12baaab0e988f155a86b9437f66e Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Mon, 26 Mar 2001 19:18:06 +0000
Subject: smbd/posix_acls.c: Saving and restoring errno here is the wrong
 place. Moved it to the places where [f]chmod_acl is called instead. Jeremy.
 (This used to be commit 641ada44ae6429761c1fd0dbcafabc69f897fac7)
