The write performance of TLC NAND is considerably lower than SLC NAND. Using SLC NAND as a WriteBooster Buffer enables the write request to be processed with lower latency and improves the overall write performance. Adds support for shared-buffer mode WriteBooster. WriteBooster enable: SW enables it when clocks are scaled up, thus it's enabled only in high load conditions. WriteBooster disable: SW will disable the feature, when clocks are scaled down. Thus writes would go as normal writes. To keep the endurance of the WriteBooster Buffer at a maximum, this load-based toggling is adopted.

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.
