Olga Kornievskaia 7c702bb4f8 nfsd: update mtime/ctime on CLONE in presense of delegated attributes
commit 2863bac7f4 upstream.

When delegated attributes are given on open, the file is opened with
NOCMTIME and modifying operations do not update mtime/ctime as to not get
out-of-sync with the client's delegated view. However, for CLONE operation,
the server should update its view of mtime/ctime and reflect that in any
GETATTR queries.

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.
