    sched/headers: Move task->mm handling methods to <linux/sched/mm.h> · 68e21be2
    Ingo Molnar authored
    Move the following task->mm helper APIs into a new header file,
    <linux/sched/mm.h>, to further reduce the size and complexity
    of <linux/sched.h>.
    
    Here are how the APIs are used in various kernel files:
