Yes, they work.

I misunderstood that the name is "cast to a user address" in the output
rather than "cast_to_user" before, there is difference between the
description and the name.

Something like this:

$ sudo ./test_progs -t jit_insns/cast_to_user
#191/2   jit_insns/cast to a user address:OK
#191     jit_insns:OK
#192     jit_insns_blinded:OK
Summary: 2/1 PASSED, 0 SKIPPED, 0/0 FAILED

Anyway, if this patch is not necessary, please ignore it.

Thanks,
