[dm-devel] [PATCH 0/6] libmultipath: check udev* func return value

[lixiaokeng]

Hi,
  The udev* function may return NULL,and it will be
dereferenced in str* and sscanf func. For example,
there is a coredump caused in add func, which show in
be7a043(commit id) in upstream-queue. We check the
return value to avoid dereference NULL.
