This patch implements an option '-u' which uses the information from the program environment when checking the device.
the function don't be found some problems.
Whiling using the command 'udevadm
test /sys/block/sdb', some error logs,
such as/sbin/multipath -u sdb'(err)
So I don't know what is that? Is
it a potential risk ? Thanks a lots.
