From 0c17ceb6f88f685e8a23019052891a198434aba8 Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Fri, 22 Aug 2014 13:32:11 +0400 Subject: [PATCH] CIFS: Fix wrong filename length for SMB2 commit 1bbe4997b13de903c421c1cc78440e544b5f9064 upstream. The existing code uses the old MAX_NAME constant. This causes XFS test generic/013 to fail. Fix it by replacing MAX_NAME with PATH_MAX that SMB1 uses. Also remove an unused MAX_NAME constant definition.
