      What were you trying to do that didn't work?

      The --trace output of qemu-img/qemu-io goes to stap instead, which is not user-friendly.

      Please provide the package NVR for which bug is seen:

      qemu-kvm-8.2.0-2.el9

      kernel-5.14.0-404.el9.x86_64

      How reproducible:

      100%

      Steps to reproduce

      $ qemu-io -f raw -c 'w -n -z 0 5g' nbd://localhost:10804 --trace=nbd_send*
      wrote 5368709120/5368709120 bytes at offset 0
      5 GiB, 1 ops; 00.04 sec (134.806 GiB/sec and 26.9612 ops/sec)

      Expected results

      There is trace output of nbd_send related events.

      Actual results

      As above
