[PATCH] sched/rt: Add comments describing the RT IPI pull method

From: "Steven Rostedt (VMware)" While looking into optimizations for the RT scheduler IPI logic, I realized that the comments are lacking to describe it efficiently. It deserves a lengthy description describing its design. Signed-off-by: Steven Rostedt (VMware) --- kernel/sched

[PATCH] sched: Update unlikely to now likely in sched_move_task()

From: "Steven Rostedt (VMware)" The check for running in sched_move_task() has an unlikely() around it. That is, it is unlikely that the task being moved is running. That use to be true. But with a couple of recent updates, it is now likely that the task will be running. The first c
