acomp's users might want to know if acomp is really async to optimize themselves. One typical user which can benefit from exposed async stat is zswap. In zswap, zsmalloc is the most commonly used allocator for (and perhaps the only one). For zsmalloc, we cannot sleep while we map the compressed memory, so we copy it to a temporary buffer. By knowing the alg won't sleep can help zswap to avoid the need for a buffer. This shows noticeable improvement in load/store latency of zswap.

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.
