-Subject: sched/fair: Fix "runnable_avg_yN_inv" not used warnings
-
-[ Upstream commit 509466b7d480bc5d22e90b9fbe6122ae0e2fbe39 ]
-
-runnable_avg_yN_inv[] is only used in kernel/sched/pelt.c but was
-included in several other places because they need other macros all
-came from kernel/sched/sched-pelt.h which was generated by
-Documentation/scheduler/sched-pelt. As the result, it causes compilation
-a lot of warnings,
-
- kernel/sched/sched-pelt.h:4:18: warning: 'runnable_avg_yN_inv' defined but not used [-Wunused-const-variable=]
- kernel/sched/sched-pelt.h:4:18: warning: 'runnable_avg_yN_inv' defined but not used [-Wunused-const-variable=]
- kernel/sched/sched-pelt.h:4:18: warning: 'runnable_avg_yN_inv' defined but not used [-Wunused-const-variable=]
- ...
-
-Silence it by appending the __maybe_unused attribute for it, so all
-generated variables and macros can still be kept in the same file.
