With journalled data it can happen that checkpointing code will write out page contents without clearing the page dirty bit. The logic in ext4_page_nomap_can_writeout() then results in us never calling mpage_submit_page() and thus clearing the dirty bit. Drop the optimization with ext4_page_nomap_can_writeout() and just always call to mpage_submit_page(). ext4_bio_write_page() knows when to redirty the page and the additional clearing & setting of page dirty bit for ordered mode writeout is not that expensive to jump through the hoops for it.

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.
