Hi Khem,

Thanks for your patch.

I've had some issues on the autobuilder for a few days, and it looks
like it was triggered by this patch. While there was no specific error,
the -tc build jobs had been running for several days and never ending.

One example:
https://autobuilder.yoctoproject.org/valkyrie/?#/builders/66/builds/2740

I've had a look on the worker: it looks like the host nfs server, used
to share files with the tests running in qemu, had been failing:

pokybui+ 4115014  1.1  0.0      0     0 ?        Z    14:23   4:32 [unfsd] <defunct>

I clearly can't see how this can be linked to this patch, yet, git
bisect points to it, and after its removal I don't have the issue
anymore.

So I'm not sure there is anything you can do, but I will accept any clue
about what might going on here.

Thanks,
Mathieu
