+Subject: [PATCH] input/item: sort before attaching slaves
+
+The order of readdir() is completely filesystem dependent.
+
+Slaves should be attached using the same order across multiple OSses/access
+modules.
+
+This fixes the test_libvlc_slaves on some system when the entry order from
+readdir() is different.
+
+This patch need to be backported to VLC 3.0.
