Subject[PATCH 16/53] sched/headers: Move 'struct pacct_struct' and 'struct cpu_itimer' form <linux/sched.h> to <linux/sched/signal.h>
Date
These structures are actually part of 'struct signal', so move them to <linux/sched/signal.h>
where they belong.

This further decreases the size and complexity of <linux/sched.h>.
