Jenkins/clang says vm_domain_rr_selectdomain(..) is unused if
VM_NUMA_ALLOC isn't defined after this commit:
https://jenkins.freebsd.org/job/FreeBSD_HEAD/250/warnings7Result/package.-887393991/source.-7253451996200343468/#55
. Could this be reduced/folded or did you mean to add more logic
around this function in the future?
Thanks,
