Again not worried about cksum-raw as Bruno's reported that. Note
that we had the df/df-symlink failure on s390x too (also reported
in a separate email).
For nocache_eof:
```
+ strace_dd if=in.f of=out.f bs=1M iflag=nocache oflag=nocache,sync
+ strace -o dd.strace -e fadvise64,fadvise64_64 dd status=none if=in.f
of=out.f bs=1M iflag=nocache oflag=nocache,sync
+ advised_to_eof
+ grep -F ' 0, POSIX_FADV_DONTNEED' dd.strace
+ fail=1
I suspect the fadvise64,fadvise64_64 strace filter isn't working on s390.
An unfiltered strace output from one of those dd commands would be useful.

Let me know if that looks like what you were expecting. All I did was
edit tests/dd/nocache_eof.sh's strace_dd to remove -e and its argument
and from a later call too.
