The acomp API allows to send requests with a NULL destination buffer. In this case, the algorithm implementation needs to allocate the destination scatter list, perform the operation and return the buffer to the user. For decompression, data is likely to expand and be bigger than the allocated buffer. Define the maximum size (128KB) that acomp implementations will allocate for decompression operations as destination buffer when they receive a request with a NULL destination buffer.

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.
