Thus, sizeof(struct cpupool) will save 8 bytes for 64-bit system.
I am happy with the change, although AFAIK cpupool is not
instantiated that often. Are you planning to have more instantiation
of it?
Cheers,
No, I'm not planning to create lots of cpupool instance.
I'm studying xen for a few weeks and my plan is:
run xen for embeded automotive use case with dom0less, null
scheduler, small code base for safety certified maybe a plus(not sure
whether can do this).
FWIW, there are discussion to get Xen safety certified. They are
captured on [1].
Cheers,

Hello Julien, Thanks for your info.
I will follow the wiki link and see what i can do about safety
certification.
