Patch 1 fixes a warning that gcc may unnecessarily emit.
Patch 2 fixes a real bug that sometimes shows up as a segfault in test-qht.
Daniel reported it yesterday on IRC; the trick to easily trigger it is to
run on RHEL6 (or CentOS6).
It is very likely that this is the test-qht failure that Peter reported here:
https://lists.nongnu.org/archive/html/qemu-devel/2016-08/msg03771.html
(we cannot be 100% sure due to the lack of output there; however the fact that
it's the resize what fails supports the hypothesis that we're indeed hitting the
same bug.)
I'm therefore adding Peter's reported-by tag to the patch along with Daniel's.
Patch 3 is merely good practice, since test-qht is single-threaded. However
I like having it, since test-qht serves as a de facto usage example
of qht.
Given that patch 2 alone would conflict without previously applying patch 1,
I propose to merge both patches 1 & 2 to 2.7-stable. I'll send them to
qemu-stable once the patchset is picked up to be merged onto master.
Thanks,
Emilio
