Currently when sfu mount option is specified then CIFS can recognize SFU symlink, but is not able to read symlink target location. readlink() syscall just returns that operation is not supported. Implement this missing functionality in cifs_sfu_type() function. Read target location of SFU-style symlink, parse it and fill into fattr's cf_symlink_target member. SFU-style symlink is file which has system attribute set and file content is buffer "IntxLNK\1" (8th byte is 0x01) followed by the target location encoded in little endian UCS-2/UTF-16. This format was introduced in Interix 3.0 subsystem, as part of the Microsoft SFU 3.0 and is used also by all later versions. Previous versions had no symlink support.

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.
