net/unix/*.c include many unnecessary header files (rtnetlink.h,
netdevice.h, etc).
Let's clean them up.
af_unix.c:
+uapi/linux/sockios.h : Only exist under include/uapi
+uapi/linux/termios.h : Only exist under include/uapi
-linux/freezer.h : No longer use freezable_schedule_timeout()
-linux/in.h : No ipv4_is_XXX() etc
-linux/module.h : No longer support CONFIG_UNIX=m
-linux/netdevice.h : No dev used
-linux/rtnetlink.h : Not part of rtnetlink API
-linux/signal.h : signal_pending() is defined in sched/signal.h
-linux/stat.h : No struct stat used
-net/checksum.h : CHECKSUM_UNNECESSARY is defined in skbuff.h
diag.c:
+linux/dcache.h : struct dentry in sk_diag_dump_vfs()
+linux/user_namespace.h : struct user_namespace in sk_diag_dump_uid()
+uapi/linux/unix_diag.h : Only exist under include/uapi/
garbage.c:
+linux/list.h : struct unix_{vertex,edge}, etc
+linux/workqueue.h : DECLARE_WORK(unix_gc_work, ...)
-linux/file.h : No fget() etc
-linux/kernel.h : No cond_resched() etc
-linux/netdevice.h : No dev used
-linux/proc_fs.h : No procfs provided
-linux/string.h : No memcpy(), kmemdup(), etc
sysctl_net_unix.c:
+linux/string.h : kmemdup()
+net/net_namespace.h : struct net, net_eq()
-linux/mm.h : slab.h is enough
