Andreas Gruenbacher 38eedf2841 gfs2: Support negative atimes
When inodes are read from disk, GFS2 will only update in-memory atimes
older than the on-disk atimes; this prevents atimes from going
backwards.  The atimes of newly allocated inodes are initialized to 0.
This means that when an atime is explicitly set to a negative value,
this value will not persist.

Fix by setting the atime of newly allocated inodes to the lowest
possible value instead of 0.

Fixes xfstest generic/258.

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
