sched: Rename sched.c as sched/core.c in comments and Documentation
Most of the stuff from kernel/sched.c was moved to kernel/sched/core.c long time
back and the comments/Documentation never got updated.
I figured it out when I was going through sched-domains.txt and so thought of
fixing it globally.
I haven't crossed check if the stuff that is referenced in sched/core.c by all
these files is still present and hasn't changed as that wasn't the motive behind
this patch.

But when you do the write-lock, you have to use the irq-safe version. For an example of being clever with rw-locks, see the "waitqueue_lock" -handling in kernel/sched.c - nothing ever _changes_ a wait-queue from +handling in kernel/sched/core.c - nothing ever _changes_ a wait-queue from within an interrupt, they only read the queue in order to know whom to wake up. So read-locks are safe (which is good: they are very common indeed), while write-locks need to protect themselves against interrupts. |
