Hi Peter, Vincent reported this problem, which is there for a while.
The first patch is cleanup as well as paving the way to the fix. Regarding the fix in the second patch, it seems the vruntime part in the detach and attach does not make sense for new task too, so I also avoided it. Thanks, Yuyang -- Yuyang Du (3): sched/fair: Clean up attach_entity_load_avg() sched/fair: Skip detach and attach new group task sched/fair: Add inline to detach_entity_load_evg() kernel/sched/auto_group.c | 2 +- kernel/sched/core.c | 8 +++--- kernel/sched/fair.c | 61 ++++++++++++++++++++++++--------------------- kernel/sched/sched.h | 4 +-- 4 files changed, 40 insertions(+), 35 deletions(-) -- 1.7.9.5
