According to kernel:Master values reported by OBS for ARM, 28G of disk
space is enough for aarch64 and 15G is enough for armv6/armv7.
28 GB for aarch64 is not very different from x86_64 so unless 35 GB constraint
results in observable problems (which doesn't seem to be the case so far), I
would prefer keeping it.
As stated in my initial e-mail, it _is_ a big problem with only 2 slow workers being able
to build kernels for ARM.
Up to 32768 MB it is ok, as a good number of build workers are usable.
As for 32-bit ARM architectures, with builds needing 15 GB at the moment, I
would suggest using something like 20 GB to give us some reserve (the
buildroot size keeps growing slowly but steadily).
20 G is fine.
I can send a patch for the update.
