[Qemu-devel] [PATCH 00/19] buffer/vnc: improve vnc buffer hsndling

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This series has a bunch of improvements in the vnc buffer handling,
to reduce the memory footprint.  Some of the changes are applied to
the buffer helper functions which Daniel separated out of the vnc code
recently.

Most patches have been on the list before, based on a older version of
Daniel's "separate out buffer code" patches.  Now I finally managed to
rebase and adapt the changes to the latest version which landed in
master meanwhile.  I don't expect major issues showing up here and plan
to have a pull request with this in time for 2.5-rc0.

Peter, if you have anything pending not yet in here please rebase and
resend.

please review,
  Gerd
