F2FS have dirty page count control for batched sequential write in writepages, and get the value of min_seq_blocks by blocks_per_seg * segs_per_sec(segs_per_sec defaults to 1). But in some scenes we set a lager section size, Min_seq_blocks will become too large to achieve the expected effect(eg. 4thread sequential write, the number of merge requests will be reduced).

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.
