commit 2e08371a83f1c06fd85eea8cd37c87a224cc4cc4 upstream. Since xfs_bmapi_convert_delalloc() only attempts to allocate the entire delalloc extent and require multiple invocations to allocate the target offset. So xfs_convert_blocks() add a loop to do this job and we call it in the write back path, but xfs_convert_blocks() isn't a common helper. Let's do it in xfs_bmapi_convert_delalloc() and drop xfs_convert_blocks(), preparing for the post EOF delalloc blocks converting in the buffered write begin path.

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.
