    Subject[PATCH 09/48] sched/headers: Prepare for new header dependencies before moving code to <linux/sched/coredump.h>
    Date
    We are going to split <linux/sched/coredump.h> out of <linux/sched.h>, which
    will have to be picked up from other headers and a couple of .c files.

    Create a trivial placeholder <linux/sched/coredump.h> file that just
    maps to <linux/sched.h> to make this patch obviously correct and
    bisectable.

    Include the new header in the files that are going to need it.
