ext4_bio_write_page does not need wbc parameter, since its parameter io contains the io_wbc field. The io::io_wbc is initialized by ext4_io_submit_init which is called in ext4_writepages and ext4_writepage functions prior to ext4_bio_write_page. Therefor, when ext4_bio_write_page is called, wbc info has already been included in io parameter.

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.
