This has been fixed in the hyperv-next branch: https://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git/log/?h=hyperv-next https://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git/commit/?h=hyperv-next&id=86e619c922e616d8780833562a14a5bda329f0c3 The fix is not in linux-next's master branch (currently it's next-20230823) yet. I believe tomorrow's linux-next would build successfully. Thanks, Dexuan
