generic/095 failing in ext4 and xfs

Hi!

I'm seeing generic/095 failing both with ext4 and xfs (but not on btrfs).
Here's what I'm getting:

# cat results/generic/095.out.bad

Silence is golden

This was for ext4 but the output for xfs is similar. Since fio is getting
killed I suspect this may be an issue with this tool. Thus I'm sending
this to both fio and fstests mailing-lists.

I'm using a 5.15-rc3 kernel and fio-3.28. Is anyone else seeing something
similar?

Cheers,
