Make rt_task() return true only for RT class and add new realtime_task() to return true for RT and DL classes to avoid some confusion the old API can cause. No functional changes intended in patch 1. Patch 2 cleans up the return type as suggested by Steve. Changes since v4: * Simplify return of rt/realtime_prio() as the explicit true/false was not necessary (Metin). Changes since v3: * Make sure the 'new' bool functions return true/false instead of 1/0. * Drop patch 2 about hrtimer usage of realtime_task() as ongoing discussion on v1 indicates its scope outside of this simple cleanup. Changes since v2: * Fix one user that should use realtime_task() but remained using rt_task() (Sebastian) * New patch to convert all hrtimer users to use realtime_task_policy() (Sebastian) * Add a new patch to convert return type to bool (Steve) * Rebase on tip/sched/core and handle a conflict with code shuffle to syscalls.c * Add Reviewed-by Steve Changes since v1: * Use realtime_task_policy() instead task_has_realtime_policy() (Peter) * Improve commit message readability about replace some rt_task() users. v1 discussion: https://lore.kernel.org/lkml/20240514234112.792989-1-qyousef@xxxxxxxxxxx/ v2 discussion: https://lore.kernel.org/lkml/20240515220536.823145-1-qyousef@xxxxxxxxxxx/ v3 discussion: https://lore.kernel.org/lkml/20240527234508.1062360-1-qyousef@xxxxxxxxxxx/ v4 discussion: https://lore.kernel.org/lkml/20240601213309.1262206-1-qyousef@xxxxxxxxxxx/ Qais Yousef (2): sched/rt: Clean up usage of rt_task() sched/rt, dl: Convert functions to return bool fs/bcachefs/six.c | 2 +- fs/select.c | 2 +- include/linux/ioprio.h | 2 +- include/linux/sched/deadline.h | 14 ++++++------- include/linux/sched/prio.h | 1 + include/linux/sched/rt.h | 33 +++++++++++++++++++++++++------ kernel/locking/rtmutex.c | 4 ++-- kernel/locking/rwsem.c | 4 ++-- kernel/locking/ww_mutex.h | 2 +- kernel/sched/core.c | 4 ++-- kernel/sched/syscalls.c | 2 +- kernel/time/hrtimer.c | 6 +++--- kernel/trace/trace_sched_wakeup.c | 2 +- mm/page-writeback.c | 4 ++-- mm/page_alloc.c | 2 +- 15 files changed, 53 insertions(+), 31 deletions(-) -- 2.34.1
