[PATCH] sched: in_sched_functions() cleanup
From: Rusty Russell <rusty@rustcorp.com.au>
1) Create an in_sched_functions() function in sched.c and make the
archs use it. (Two archs have wchan #if 0'd out: left them alone).
2) Move __sched from linux/init.h to linux/sched.h and add comment.
3) Rename __scheduling_functions_start_here/end_here to __sched_text_start/end.
Thanks to wli and Sam Ravnborg for clue donation.
