Olga Kornievskaia 28568c906c NFSv4.1 enforce rootpath check in fs_location query 
In commit 4ca9f31a2b ("NFSv4.1 test and add 4.1 trunking transport"),
we introduce the ability to query the NFS server for possible trunking
locations of the existing filesystem. However, we never checked the
returned file system path for these alternative locations. According
to the RFC, the server can say that the filesystem currently known
under "fs_root" of fs_location also resides under these server
locations under the following "rootpath" pathname. The client cannot
handle trunking a filesystem that reside under different location
under different paths other than what the main path is. This patch
enforces the check that fs_root path and rootpath path in fs_location
reply is the same.

Fixes: 4ca9f31a2b ("NFSv4.1 test and add 4.1 trunking transport")

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.
