With the strictlimit flag, wb_thresh acts as a hard limit in balance_dirty_pages() and wb_position_ratio(). When device write operations are inactive, wb_thresh can drop to 0, causing writes to be blocked. The issue occasionally occurs in fuse fs, particularly with network backends, the write thread is blocked frequently during a period. To address it, this patch raises the minimum wb_thresh to a controllable level, similar to the non-strictlimit case.

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.
