From 3ee6bd8e8dc0c58b9ba5bab7ef8a7a131da346eb Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 27 Jan 2012 19:14:58 +0100 Subject: uml/hostfs: Propagate dirent.d_type to filldir() Currently the (optional) d_type member in struct dirent is always DT_UNKNOWN on hostfs, which may confuse buggy software using readdir(). Make sure to propagate its value from the underlying filesystem if it's available there.
