[dm-devel] [PATCH] multipath: strdup multipath alias, so that it isn't deleted.

[Benjamin Marzinski <bmarzins redhat com>]

When a multipath device is added to multipathd with ev_add_map(),
the alias is not duplicated, and is freed immediately after ev_add_map()
returns, causing a memory error. This patch corrects that.
