[dm-devel] [PATCH] Memory leak when deleting and re-adding device-mapper entries.

From: Konrad Rzeszutek <konrad at mars.virtualiron.com>

 If we remove a map (with configuration details specified in the multipath.conf file)
 and later re-add it, the pointer to the config is over-written without first
 de-allocating the values.
