Actually, it's an open question whether we still want to keep CONFIG_PREEMPT or not on other archs, too. CONFIG_PREEMPT hits performance significantly. I don't know much about other distros, but IIRC, Fedora is using CONFIG_PREEMPT_VOLUNTARY instead. Ubuntu provide both non-preempt and CONFIG_PREEMPT versions? Correct me if wrong.
It also aligns to default arm64 kernel config.
That's more convincing reason in this case, though :) thanks, Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
