linux-next: manual merge of the vfs-brauner tree with the ksmbd tree

Hi all,

Today's linux-next merge of the vfs-brauner tree got conflicts in:

  fs/smb/server/smb2pdu.c
  fs/smb/server/vfs.c
  fs/smb/server/vfs.h

between commits:

  a0115a20ecc50 ("ksmbd: fix invalid pointer dereference when get_inode_acl() fails")
  1be59204ab530 ("ksmbd: copy stream content when renaming to a new stream name")
  a90dd07b4dfb3 ("ksmbd: look up stream size by exact xattr name")

from the ksmbd tree and commits:

  16d90b57d8439 ("fs: port xattr to const mnt_idmap")
  0c18a70900eee ("fs: port i_{g,u}id_into_vfs{g,u}id() to const mnt_idmap")

from the vfs-brauner tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
