From dedefd7215d3ec451291ca393e5c8e4c1882c8c6 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 24 Jan 2011 21:43:18 +0000 Subject: [PATCH] Btrfs: fix check_path_shared so it returns the right value When running xfstests 224 I kept getting ENOSPC when trying to remove the files, and this is because we were returning ret from check_path_shared while it was uninitalized, which isn't right. Fix this to return 0 properly, and now xfstests 224 doesn't freak out when it tries to clean itself up.
