[Qemu-devel] [PATCH 00/20] chardev flow control

[Amit Shah <amit.shah@redhat.com>]

Changes from Anthony's earlier series:
* Added patch 20 that makes flow control explicit in virtio-console
* Fixed compile error in patch 13, "qemu-char: make char drivers
  dynamically registerable", which had a wrong 'fix' in unrelated
  patch 16.
* rebased to master

Please apply.

Orig. message from Anthony for this series:

This series implements an idea from Paolo to introduce flow control
in the char layer by converting all char backends to use GIOChannels
internally.  Then we can just use the existing IO watch support in glib
to implement flow control.

This is based on a rebased version of an old series of mine plus a
number of improvements from Amit Shah.
