Hi, All,
Very appreciated for your time on reviewing our patch.
The second CI failure caused by our patch has been addressed. One simple
way is moving "#endif" in qemu/tests/bench/xbzrle-bench.c from line 46 to line
450.
We have submitted patch v7 to update this modification. Thanks for your time
again.
Best Regards,
Ling

I think the issue is that the test links against objects that aren't present
when qemu-user only build is performed. That's my first guess, I might be wrong
but it is definitely this commit that causes the failure (I bisected it).
There is a second CI failure here:
