+Subject: [PATCH] multipathd: remove coalesce_paths from ev_add_map
+
+If ev_add_map is called for a multipath device that doesn't exist in
+device-mapper, it will call coalesce_paths to add it.  This doesn't work
+and hasn't for years. It doesn't add the map to the mpvec, or start up
+waiters, or do any of the necessary things that do get done when you
+call ev_add_map for a map that does exist in device mapper.
+
+Fortunately, there are only two things that call ev_add_map. uev_add_map
+makes sure that the device does exist in device-mapper before calling
+ev_add_map, and cli_add_map creates the device first and then calls
+ev_add_map, if the device doesn't exist.
+
+So, there is no reason for coalesce_paths to be in ev_add_map. This
+removes it.
