Linux kernel source tree
138336d674
Patch series "mm/zswap: misc cleanup of code and documentations". Clean up an unnecessary local variable write in incompressible pages handling, typos (s/zwap/zswap/) and outdated comments/documentations about the zswap's red-black tree, which is replaced by xarray. This patch (of 4): Incompressible pages handling logic in zswap_compress() is setting 'dlen' as PAGE_SIZE twice. Once before deciding whether to save the content as is, and once again after it is decided to save it as is. But the value of 'dlen' is used only if it is decided to save the content as is, so the first write is unnecessary. It is not causing real user issues, but making code confusing to read. Remove the unnecessary write operation.

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.
