From b12be99c8925e758554076c87294b4af10ebf05e Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 1 Mar 2011 13:39:43 -0600 Subject: Ensure d_type is not DT_UNKNOWN before relying on it Fixes FS#23090, a rather serious problem where the user was completely unable to read the local database. Even if entry->d_type is available, the given filesystem providing it may not fill the contents, in which case we should fall back to a stat() as we did before. In this case, the filesystem was XFS but there may be others.
