From 686ea46cbc9538355815fe800e441d67fee6a9db Mon Sep 17 00:00:00 2001
From: Volker Lendecke <vl@samba.org>

Subject: [PATCH] libsmb: Don't try to find posix stat info in SMBC_getatr()
This wrongly used "frame" instead of "fname", which can never have
worked. A first attempt to fix in 51551e0d53fa6 caused a few followup
patches in an attempt to clean up the test failures 51551e0d53fa6
introduced. They were reverted after a few discussions. So rather than
changing behaviour, just remove the code that introduced the valgrind
error again.
