From 02d8ec9456f47b8865f1ff3fbb532e12a760d3b5 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 3 Mar 2018 16:27:54 +0100 Subject: sched/deadline, rt: Rename queue_push_tasks/queue_pull_task to create separate namespace There are similarly named functions in both of these modules: kernel/sched/deadline.c:static inline void queue_push_tasks(struct rq *rq) kernel/sched/deadline.c:static inline void queue_pull_task(struct rq *rq) kernel/sched/deadline.c:static inline void queue_push_tasks(struct rq *rq) kernel/sched/deadline.c:static inline void queue_pull_task(struct rq *rq) kernel/sched/deadline.c: queue_push_tasks(rq); kernel/sched/deadline.c: queue_pull_task(rq); kernel/sched/deadline.c: queue_push_tasks(rq); kernel/sched/deadline.c: queue_pull_task(rq); kernel/sched/rt.c:static inline void queue_push_tasks(struct rq *rq) kernel/sched/rt.c:static inline void queue_pull_task(struct rq *rq) kernel/sched/rt.c:static inline void queue_push_tasks(struct rq *rq) kernel/sched/rt.c: queue_push_tasks(rq); kernel/sched/rt.c: queue_pull_task(rq); kernel/sched/rt.c: queue_push_tasks(rq); kernel/sched/rt.c: queue_pull_task(rq); ... which makes it harder to grep for them. Prefix them with deadline_ and rt_, respectively.
