[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v2 13/26] xen/domctl: wrap sched_adjust() with CONFIG_MGMT_HYPERCALLS
Function sched_adjust() is responsible for XEN_DOMCTL_scheduler_op domctl-op,
so it could be wrapped with CONFIG_MGMT_HYPERCALLS.
Tracing its calling chain, the following functions shall be wrapped with
CONFIG_MGMT_HYPERCALLS too:
- sched_adjust_dom()
- scheduler-specific .adjust() callback
- xsm_sysctl_scheduler_op()
Wrap XEN_DOMCTL_scheduler_op-case transiently with CONFIG_MGMT_HYPERCALLS,
and it will be removed when introducing CONFIG_MGMT_HYPERCALLS on the
common/domctl.c in the last.
Signed-off-by: Penny Zheng <Penny.Zheng@xxxxxxx>
---
v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- wrap XEN_DOMCTL_scheduler_op-case transiently
