[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 2/9] xen/sched: make sched-if.h really scheduler private
include/xen/sched-if.h should be private to scheduler code, so move it
to common/sched/private.h and move the remaining use cases to
cpupool.c and core.c.
Signed-off-by: Juergen Gross <jgross@xxxxxxxx>
Reviewed-by: Dario Faggioli <dfaggioli@xxxxxxxx>

V2:
- rename to private.h (Andrew Cooper)
