Since timestamps on files on most servers can be updated at close, and since timestamps on our dentries default to one second we can have stale timestamps in some common cases (e.g. open, write, close, stat, wait one second, stat - will show different mtime for the first and second stat). The SMB2/SMB3 protocol allows querying timestamps at close so add the code to request timestamp and attr information (which is cheap for the server to provide) to be returned when a file is closed (it is not needed for the many paths that call SMB2_close that are from compounded query infos and close nor is it needed for some of the cases where a directory close immediately follows a directory open.

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 Restructured Text 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.
