There were two problems (one of which could cause data corruption) that were noticed with duplicate extents (ie reflink) when debugging why various xfstests were being incorrectly skipped (e.g. generic/138, generic/140, generic/142). First, we were not updating the file size locally in the cache when extending a file due to reflink (it would refresh after actimeo expires) but xfstest was checking the size immediately which was still 0 so caused the test to be skipped. Second, we were setting the target file size (which could shrink the file) in all cases to the end of the reflinked range rather than only setting the target file size when reflink would extend the file.

README
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.
