The above is the specific instance on your environment. Mine is
different: different kernel major/minor device numbers for /dev/urandom
and /dev/random.
I got the definition from
man 4 random
If your /dev/urandom never blocks the requesting task irrespective of
the random bytes usage, then maybe your /dev/random is not as secure as
it might be (unless you have an high speed entropy source, but what is
"high speed" in this context?)
