Thanks for pointing out the C source.  I was looking at the original syzkaller
reproducer [1] which IMHO did more things, simplified C source is quite similar
to what you do in LTP test.

Have you verified if it actually reproduce the bug on affected kernel? Does it
reproduce the bug?

I tried it only on too new kernel (6.12 based SLE16 kernel, required to install
rdma-core, rdma_cm kernel module, which creates /dev/infiniband/rdma_cm, was
loaded by default).

Kind regards,
Petr
