In the event that we can't fetch post_op_attr attributes, we still need to set a value for the after_change. The operation has already happened, so we're not able to return an error at that point, but we do want to ensure that the client knows that its cache should be invalidated. If we weren't able to fetch post-op attrs, then just set the after_change to before_change + 1. The atomic flag should already be clear in this case.

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.
