Since now flush_write_bio() could return error, kill the BUG_ON() first. Then don't call flush_write_bio() unconditionally, instead we check the return value from __extent_writepage() first. If __extent_writepage() fails, we do cleanup, and return error without submitting the possible corrupted or half-baked bio. If __extent_writepage() successes, then we call flush_write_bio() and return the result.

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.
