sched/headers: Move 'struct pacct_struct' and 'struct cpu_itimer' form... (8d88460e) · Commits · 戴 / test

sched/headers: Move 'struct pacct_struct' and 'struct cpu_itimer' form <linux/sched.h> to <linux/sched/signal.h> 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>. Acked-by:
