For several zoned storage devices, vendors will provide extra space which was used for device level GC than specs and F2FS can use this space for filesystem level GC. To do that, we can reserve the space using reserved_blocks. However, it is not enough, since this extra space should not be shown to users. So, with this new sysfs node, we can hide the space by substracting reserved_blocks from total bytes.

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.
