For NOCOW files, run_delalloc_nocow can still fall back to COW allocations when required and calls to fallback_to_cow helper for that. For such an allocation we can have multiple ordered_extents for existing extents that NOCOW overwrites and new allocations that fallback_to_cow creates. If one of the new extents is an inline extent, the writepages could would have to avoid normal page writeback for them as indicated by the page_started return argument, which run_delalloc_nocow can't return. Fix this by never creating inline extents from fallback_to_cow.

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.
