Paulo Alcantara a21406d314 smb: client: don't try following DFS links in cifs_tree_connect()
[ Upstream commit 36008fe6e3 ]

We can't properly support chasing DFS links in cifs_tree_connect()
because

  (1) We don't support creating new sessions while we're reconnecting,
      which would be required for DFS interlinks.

  (2) ->is_path_accessible() can't be called from cifs_tree_connect()
     as it would deadlock with smb2_reconnect().  This is required for
     checking if new DFS target is a nested DFS link.

By unconditionally trying to get an DFS referral from new DFS target
isn't correct because if the new DFS target (interlink) is an DFS
standalone namespace, then we would end up getting -ELOOP and then
potentially leaving tcon disconnected.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
