This patch enables f2fs_balance_fs_bg() to check all metadatas' dirty threshold rather than just checking node block's, so that checkpoint() from background can be triggered more frequently to avoid heaping up too much dirty metadatas. Threshold value by default: race with foreground ops single type global No 16MB 24MB Yes 24MB 36MB In addtion, let f2fs_balance_fs_bg() be aware of roll-forward sapce as well as fsync().

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.
