The long and obscure command line is a red herring: a simple
"modprobe test_xarray" is all it takes...

BTW, how do I even build tools/testing/radix-tree?
"make tools/help" doesn't show the radix-tree test.
"make tools/all" doesn't seem to try to build it.
Same for "make kselftest-all".
When trying the above, and ignoring failures due to missing packages
on my host:
  - there are several weird build errors,
  - this doesn't play well with O=,
  - lots of scary warnings when building for 32-bit,
  - ...

At least the kunit tests build (and run[1] ;-) most of the time...

[1] test_xarray started failing on m68k recently

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
