devices that we also support, just not by default (thus only LINT or module builds by default). While currently there is only "/dev/full" [2], we are planning to see more in the future. We may decide to change the module/dependency logic in the future should the list grow too long. This is not part of linux.ko as also non-linux binaries like kFreeBSD userland or ports can make use of this as well.

# of robustness to overloads and responsivity, as well as permitting
