2021-02-08event_notifier: handle initialization failure betterMaxim Levitsky1-0/+1
Add 'initialized' field and use it to avoid touching event notifiers which are either not initialized or if their initialization failed. This is somewhat a hack, but it seems the less intrusive way to make virtio code deal with event notifiers that failed initialization.

2018-01-18qemu: add a cleanup callback function to EventNotifierGal Hammer1-0/+1
Adding a cleanup callback function to the EventNotifier struct which allows users to execute event_notifier_cleanup in a different context. Signed-off-by: Gal Hammer <ghammer@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2017-01-16event_notifier: cleanups around event_notifier_set_handlerPaolo Bonzini1-3/+0
Remove the useless is_external argument. Since the iohandler AioContext is never used for block devices, aio_disable_external is never called on it. This lets us remove stubs/iohandler.c. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-04-22event-notifier: Add "is_external" parameterFam Zheng1-1/+3
All callers pass "false" keeping the old semantics. The windows implementation doesn't distinguish the flag yet. On posix, it is passed down to the underlying aio context.
