[Xen-devel] [PATCH RFC UNTESTED 30/28] squash! libxl: cancellation: Provide public ao cancellation API

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

[ In v4 of the series I will combine this fixup with the named patch
  using git-rebase -i --autosquash -iwj. ]

v4: Actually record aos on aos_inprogress.
    (Report from Koushik Chakravarty at Citrix.)
