This is the counterpart of the previous patch: here, we extract buffer writing with attributes from vcs_write. Now, there is no need for org to be initialized to NULL. The org0 check before update_region() confuses compilers, so check org instead. It provides the same semantics. And it also eliminates the need for initialization of org0. We switch the branches of the attr 'if' too, as the inversion brings only confusion now.

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.
