Yay, I like it when it's not my fault. I'll redo it with the ifdef
CONFIG_NO_HZ_FULL.
What should it do for the !CONFIG_NO_HZ_FULL case? The existing call in
guest_enter_irqoff() clearly wasn't actually doing the right thing
anyway, hence the need for the need_resched() patch in $SUBJECT... so
should I just leave it doing nothing in guest_enter_irqoff()?ÂAttachment:
