Recently, I switched over from swap-file to zramswap. When reading the Documentation/vm/zswap.rst file I fell over this typo. The parameter is called accept_threshold_percent not accept_threhsold_percent in /sys/module/zswap/parameters/ directory.

This is a first pass at updating the basic documentation on Linux Security Modules (LSM), which is frighteningly out of date. Remove untrue statements about the LSM framework. Replace them with true statements where it is convenient to do so. This is the beginnig of a larger effort to bring the LSM documentation up to date.

During recent patch discussion [1] it became apparent that the "other_node" definition in the numastat documentation has always been different from actual implementation. It was also noted that the stats can be innacurate on systems with memoryless nodes. This patch corrects the other_node definition (with minor tweaks to two more definitions), adds a note about memoryless nodes and also two introductory paragraphs to the numastat documentation.

A routine check for misspelled Kconfig symbols showed on instance from last year, the correct symbol name is CONFIG_ANDROID_BINDERFS, not CONFIG_CONFIG_ANDROID_BINDERFS, so the extra prefix must be removed in the Kconfig file to allow enabling the sample.

Mauro says: This is the second part of a series I wrote sometime ago where I manually convert lots of files to be properly parsed by Sphinx as ReST files. As it touches on lot of stuff, this series is based on today's linux-next, at tag next-20190617. The first version of this series had 57 patches. The first part with 28 patches were already merged. Right now, there are still ~76 patches pending applying (including this series), and that's because I opted to do ~1 patch per converted directory. That sounds too much to be send on a single round. So, I'm opting to split it on 3 parts for the conversion, plus a final patch adding orphaned books to existing ones. Those patches should probably be good to be merged either by subsystem maintainers or via the docs tree. I opted to mark new files not included yet to the main index.rst (directly or indirectly) with the :orphan: tag, in order to avoid adding warnings to the build system. This should be removed after we find a "home" for all the converted files within the new document tree arrangement, after I submit the third part.
