Overview: [PATCH 1/6] - Remove `struct dl_bandwidth def_dl_bandwidth`. [PATCH 2/6] - Move functions into DL sched class which don't have to be exported. [PATCH 3/6] - Merge two DL admission control functions which provide very similar functionality. [PATCH 4/6] - Use DL rb_entry() macros and cached rbtree wrapper `rb_first_cached()` consistently. [PATCH 5/6] - Remove unused !CONFIG_SMP function definitions in DL/RT. [PATCH 6/6] - Remove redundant function parameter in DL/RT. Dietmar Eggemann (6): sched/deadline: Remove unused def_dl_bandwidth sched/deadline: Move bandwidth mgmt and reclaim functions into sched class source file sched/deadline: Merge dl_task_can_attach() and dl_cpu_busy() sched/deadline: Use __node_2_[pdl|dle]() and rb_first_cached() consistently sched/deadline,rt: Remove unused functions for !CONFIG_SMP sched/deadline,rt: Remove unused parameter from pick_next_[rt|dl]_entity() kernel/sched/core.c | 14 ++-- kernel/sched/deadline.c | 141 ++++++++++++++++++++-------------------- kernel/sched/rt.c | 16 +---- kernel/sched/sched.h | 53 +-------------- 4 files changed, 84 insertions(+), 140 deletions(-) -- 2.25.1
