Now when we allocate blocks on write page fault there should be no block allocation happening on page writeback. So just ignore the 'create' flag passed to udf_get_block(). Note that we can spot dirty buffers without underlying blocks allocated in writeback when we race with expanding truncate. However in that case these buffers do not contain valid data so we can safely ignore them and we would just create ourselves problem when to trim the tail extent.

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.
