Zhang Yi cd9f76de6a ext4: make the writeback path support large folios
In mpage_map_and_submit_buffers(), the 'lblk' is now aligned to
PAGE_SIZE. Convert it to be aligned to folio size. Additionally, modify
the wbc->nr_to_write update to reduce the number of pages in a single
folio, ensuring that the entire writeback path can support large folios.

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 reStructuredText 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.
