Subject: af_unix: Explicitly include headers for non-pointer struct fields.
X-Git-Tag: v6.15-rc1~160^2~35^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3056172a261c88fc834147f6427b09dfe4d4290b;p=thirdparty%2Fkernel%2Flinux.git

af_unix: Explicitly include headers for non-pointer struct fields.

include/net/af_unix.h indirectly includes some definitions for structs.

Let's include such headers explicitly.

  linux/atomic.h   : scm_stat.nr_fds
  linux/net.h      : unix_sock.peer_wq
  linux/path.h     : unix_sock.path
  linux/spinlock.h : unix_sock.lock
  linux/wait.h     : unix_sock.peer_wake
  uapi/linux/un.h  : unix_address.name[]

linux/socket.h is removed as the structs there are not used directly,
and linux/un.h is clarified with uapi as un.h only exists under
include/uapi.

While at it, duplicate headers are removed from .c files.
