In some conditions(such as umount fs failed),origin path or origin bdev or both
of the two is same
as cow's.If this happens, origin dev will be freed when get cow dev in function
"dm_get_device" ,
then "s->origin->dev" which used by "dm_exception_store_create" will be a NULL
pointer.
In some conditions(such as umount fs failed),origin path or origin bdev or both
of the two is same
as cow's.If this happens, origin dev will be freed when get cow dev in function
"dm_get_device" ,
then "s->origin->dev" which used by "dm_exception_store_create" will be a NULL
pointer.
