When ->iomap_end is called on a short write to the COW fork it needs to punch stale delalloc data from the COW fork and not the data fork. Ensure that IOMAP_F_NEW is set for new COW fork allocations in xfs_buffered_write_iomap_begin, and then use the IOMAP_F_SHARED flag in xfs_buffered_write_delalloc_punch to decide which fork to punch.

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.
