Hi,

I am changing the credit1 scheduler. But I encountered a problem that the system will crash if I use some fileds of struct csched_dom (e.t. sdom->weight, sdom->credit ) frequently in the csched_vcpu_acct() or csched_runq_sort(). It seems strange. Can anyone give me some suggestion or share your experience? Thanks.

Regards,
Cong
