This test really wants to test partial file-system block I/Os. Thus, if the device has a 4K sector size, and the file system has a 4K block size, there's really no point in running the test. In the attached patch, I check that the fs block size is larger than the device's logical block size, which should cover a 4k device block size with a 16k fs block size. I verified that the patched test does not run on my 4k sector device with a 4k file system. I also verified that it continues to run on a 512 byte logical sector device with a 4k file system block size.

# Test that non-block-aligned aio+dio into holes does not leave

# QEMU IO to a file-backed device with misaligned partitions

# This test need only be run in the case where the logical block size
