Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

fs/cifs/cifs_swn.c: In function 'cifs_swn_notify':
fs/cifs/cifs_swn.c:450:4: error: implicit declaration of function 'nla_strlcpy'; did you mean 'nla_strscpy'? [-Werror=implicit-function-declaration]
  450 |    nla_strlcpy(name, info->attrs[CIFS_GENL_ATTR_SWN_RESOURCE_NAME],
      |    ^~~~~~~~~~~
      |    nla_strscpy

Caused by commit

  872f69034194 ("treewide: rename nla_strlcpy to nla_strscpy.")

interacting with commit

  27228d73f4d2 ("cifs: Set witness notification handler for messages from userspace daemon")

from the cifs tree.

I have applied the following merge fix patch.

Date: Mon, 14 Dec 2020 13:09:27 +1100
Subject: [PATCH] fixup for "treewide: rename nla_strlcpy to nla_strscpy."
