Hello,
DESCRIPTION
This patchset fixes old problem with hungup of both rx/tx sides and adds
test for it. This happens due to non-default SO_RCVLOWAT value and
deferred credit update in virtio/vsock. Link to previous old patchset:
https://lore.kernel.org/netdev/39b2e
Send credit update message when SO_RCVLOWAT is updated and it is bigger
than number of bytes in rx queue. It is needed, because 'poll()' will
wait until number of bytes in rx queue will be not smaller than
SO_RCVLOWAT, so kick sender to send more data. Otherwise mutual hungup
for tx/rx is possible:

Hi Ilya,
Sorry for this taking so long, I'll probably take a closer look next week.
Overall, the s390 part looks good to me, but I wanted to check the x86
behavior once again (and perhaps figure out how to avoid introducing
another way to disable KMSAN).
