[Qemu-devel] [PATCHv2 0/3] virtio-serial-bus: use a bh for flush_queued_data

[Alon Levy <alevy@redhat.com>]

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
