The check should be against concrete version (0x10000 in this case).

Stepping back: what does the version mean?

0x10000 == 1.0 ?
0x10001 == 1.1 ?

Can I expect the interface stay backward compatible if only the minor revision
changes, i.e. makes it sense to accept 1.x?

Will the major revision ever change?  Does it make sense to check the version at
all?

As already established earlier in this thread,
by Linus Torvalds as well as by myself,
NO!

That whole "version" concept is broken and inappropriate.
Userspace should simply ignore it completely.
