-Subject: [PATCH 39/40] mapfile: set *mapp to NULL after map_free
-
-We can see "double free or corruption" with below steps
-as reported by Mariusz:
-
-export IMSM_NO_PLATFORM=1
-export IMSM_DEVNAME_AS_SERIAL=1
-mdadm --zero-super /dev/sd*
-mdadm -C /dev/md/imsm -n2 -eimsm /dev/sdb /dev/sdc --run
-mdadm -C /dev/md/r1 -n2 -z15G -eimsm /dev/sdb /dev/sdc -l1 --run --assume-clean
-mdadm -f /dev/md126 /dev/sdb
-mdadm -Ss
-
-It is caused by Manage_stop calls map_remove and map_unlock,
-but *mapp is not set to NULL after map_remove -> map_free,
-so map_unlock will call map_free again.
