The 2 patches should go in v4.16. They should go in old stable kernels too, especially this one should go in v4.15: PCI: hv: Fix 2 hang issues in hv_compose_msi_msg() Otherwise, a UP v4.15 VM can 100% hang when we pass through a VF to the VM that runs on Hyper-V. There is no code change since v3: https://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg1628496.html I just split the original 6 patches to 2 series, and this is series 1. I fixed the order of Signed-off-by/Tested-by/Cc, etc., and added a Fixes: tag, and fixed the other format issues in changelog. I hope I didn't omit anything this time. :-) Dexuan Cui (2): PCI: hv: Serialize the present and eject work items PCI: hv: Fix 2 hang issues in hv_compose_msi_msg() drivers/pci/host/pci-hyperv.c | 75 ++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 71 insertions(+), 4 deletions(-) -- 2.7.4
