Archdevs,

Update tonight to 4.12.3-1, and for the first time in years, DKMS failed to rebuild the VirtualBox kernel modules. Specifically attempting a manual install/build resulted in:

# dkms install -m vboxhost -v 5.1.22

Kernel preparation unnecessary for this kernel. Skipping...

Building module: cleaning build area... make -j8 KERNELRELEASE=4.12.3-1-ARCH -C /usr/lib/modules/4.12.3-1-ARCH/build M=/var/lib/dkms/vboxhost/5.1.22/build....(bad exit status: 2) Error! Bad return status for module build on kernel: 4.12.3-1-ARCH (x86_64) Consult /var/lib/dkms/vboxhost/5.1.22/build/make.log for more information.

Is this known, expected, or do we need to open a bug?

The error from the log centers around:
