[Qemu-devel] [PATCH v6 0/5] event: Add source information to SHUTDOWN

[Eric Blake]

v2 was here:
https://lists.gnu.org/archive/html/qemu-devel/2017-04/msg03185.html
v3 and v4 were dead on arrival
v5 was here:
https://lists.gnu.org/archive/html/qemu-devel/2017-04/msg05564.html

Since then:
- rework the enum to be internal only
- add a 'none' slot to the enum, so that we are back to comparison
to 0 rather than -1 as the no-request-yet state
- drop the RFC patch that would expose the reasons through QAPI (Dan's
take, at least on IRC, is that even with finer-grained reasons from
qemu, the most libvirt would do is log the reason and then still just
expose a boolean higher up).  We can revive that patch if desired, but
doing so also implies adding a 'query-shutdown' command, and I didn't
think it was worth it for now (no need to over-engineer until we know
we have a client that wants it)
- fix replay to preserve status
- split the patches slightly differently, so that internal wiring and
event additions are separated

Eric Blake (5):
  shutdown: Simplify shutdown_signal
  shutdown: Prepare for use of an enum in reset/shutdown_request
  shutdown: Add source information to SHUTDOWN and RESET
  shutdown: Preserve shutdown cause through replay
  shutdown: Expose bool cause in SHUTDOWN and RESET events
