This replaces the direct call of flush_queued_data with a bottom half,
making the callpath for the chardev identical in a normal write and a write
resulting from unthrottling.
It includes a patch to add an accessor to QEMUBH to get scheduled status,
to keep the bh scheduled across migration.
Migration only trivially tested - just that it didn't break.
Alon Levy (3):
virtio-serial-bus: use bh for unthrottling
bh: add qemu_bh_is_scheduled
virtio-serial-bus: on migration send status of pending ports bh
