Hi Markus,
Yeah these positive errno values have been sitting there since the
beginning. It was dead code until I hijacked the synth backend to
implement qtest for 9p. I didn't care much about the return value
of the two culprits at the time since both are passed to assert(!ret)
right away. For this reason, changing the sign should be easy :-)
I see that checkpatch.pl considers this as an error. I'll post
a fix. I guess you'll need to rebase on this fix for your patches
to pass CI.
Anyway, for 9p:
