[PATCH v3 0/9] virtio: console: fixes for bugs and races with unplug
Hello,
This series fixes a few bugs and races with port unplug and the
various file operations: read(), write() and close().
I started coding up an alternative locking mechanism based on the
discussion earlier in this series, but some of what we already have
has to remain, and the new code is sufficiently different, so I'd
rather it bakes for a while, and I ensure there are no regressions

[PATCH 00/10] virtio: console: fixes for races with port unplug
Hello,
This series fixes a few races with port unplug and the various file
operations: read(), write(), close() and poll().
There still might be more races lurking, but testing this series looks
good to at least solve the easily-triggerable ones. I've run the
virtio-serial testsuite and a few open/close/unplug tests, and haven't
seen any badness.
