In commit 6b55c9654fcc ("sched/debug: Move print_cfs_rq() declaration to
kernel/sched/sched.h"), ‘print_cfs_rq’ prototype was added to
<kernel/sched/sched.h> right next to prototypes for ‘print_cfs_stats’,
‘print_rt_stats’ and ‘print_dl_stats’. Update this previous commit
and also move related prototypes: ‘print_rt_rq’ and ‘print_dl_rq’.
Remove existing extern declarations now that they not needed anymore.
Silence the following gcc warning, triggered at W=1:
kernel/sched/debug.c:573:6: warning: no previous prototype for ‘print_rt_rq’ [-Wmissing-prototypes]
kernel/sched/debug.c:603:6: warning: no previous prototype for ‘print_dl_rq’ [-Wmissing-prototypes]

sched/debug: Move the print_rt_rq() and print_dl_rq() declarations to kernel/sched/sched.h
In the following commit:
6b55c9654fcc ("sched/debug: Move print_cfs_rq() declaration to kernel/sched/sched.h")
the print_cfs_rq() prototype was added to <kernel/sched/sched.h>,
right next to the prototypes for print_cfs_stats(), print_rt_stats()
and print_dl_stats().
Finish this previous commit and also move related prototypes for
print_rt_rq() and print_dl_rq().
Remove existing extern declarations now that they not needed anymore.
Silences the following GCC warning, triggered by W=1:
kernel/sched/debug.c:573:6: warning: no previous prototype for ‘print_rt_rq’ [-Wmissing-prototypes]
kernel/sched/debug.c:603:6: warning: no previous prototype for ‘print_dl_rq’ [-Wmissing-prototypes]
