This test and vectored_zvol_poll appear to be failing in CI recently (https://ci.freebsd.org/job/FreeBSD-main-amd64-test/19158/testReport/junit/sys.aio/aio_test/vectored_unaligned/). Any ideas why this could be happening?

I am not sure if it has ever succeeded in CI, most previous runs show it as skipped.

No, and I can't reproduce that failure myself. It might be a race condition in ZFS, or maybe for some other reason the zvol doesn't have the expected name.
