2018-08-02Merge branch 'rppt' into docs-nextJonathan Corbet1-0/+1
This contains a set of early-boot memory-management docs from Mike Rapoport. It's been circulating on linux-mm for a long time; I finally picked it up even though it changes a lot of .c files under mm/ (comments only).
2018-08-02docs/mm: add description of boot time memory managementMike Rapoport1-0/+1
Both bootmem and memblock are have pretty good internal documentation coverage. With addition of some overview we get a nice description of the early memory management.

2018-07-23Documentation: document ktime_get_*() APIsArnd Bergmann1-0/+1
As Dave Chinner points out, we don't have a proper documentation for the ktime_get() family of interfaces, making it rather unclear which of the over 30 (!) interfaces one should actually use in a driver or elsewhere in the kernel. I wrote up an explanation from how I personally see the interfaces, documenting what each of the functions do and hopefully making it a bit clearer which should be used where. This is the first time I tried writing .rst format documentation, so in addition to any mistakes in the content, I probably also introduce nonstandard formatting ;-) I first tried to add an extra section to Documentation/timers/timekeeping.txt, but this is currently not included in the generated API, and it seems useful to have the API docs as part of what gets generated in https://www.kernel.org/doc/html/latest/core-api/index.html#core-utilities instead, so I started a new file there. I also considered adding the documentation inline in the include/linux/timekeeping.h header, but couldn't figure out how to do that in a way that would result both in helpful inline comments as well as readable html output, so I settled for the latter, with a small note pointing to it from the header.

2018-05-29doc: document scope NOFS, NOIO APIsMichal Hocko1-0/+1
Although the api is documented in the source code Ted has pointed out that there is no mention in the core-api Documentation and there are people looking there to find answers how to use a specific API.

2018-01-01errseq: Add to documentation treeMatthew Wilcox1-0/+1
- Move errseq.rst into core-api - Add errseq to the core-api index - Promote the header to a more prominent header type, otherwise we get three entries in the table of contents. - Reformat the table to look nicer and be a little more proportional in terms of horizontal width per bit (the SF bit is still disproportionately large, but there's no way to fix that). - Include errseq kernel-doc in the errseq.rst - Neaten some kernel-doc markup Signed-off-by: Matthew Wilcox <mawilcox@microsoft.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Reviewed-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2017-12-21doc: convert printk-formats.txt to rstTobin C. Harding1-0/+1
Documentation/printk-formats.txt is a candidate for conversion to ReStructuredText format. Some effort has already been made to do this conversion even thought the suffix is currently .txt Changes required to complete conversion - Move printk-formats.txt to core-api/printk-formats.rst - Add entry to Documentation/core-api/index.rst - Remove entry from Documentation/00-INDEX - Fix minor grammatical errors. - Order heading adornments as suggested by rst docs. - Use 'Passed by reference' uniformly. - Update pointer documentation around %px specifier. - Fix erroneous double backticks (to commas). - Remove extraneous double backticks (suggested by Jonathan Corbet). - Simplify documentation for kobject.

A couple of the most minor heading tweaks, otherwise no changes to the text itself beyond the mechanical conversion. Note that the inclusion of the kerneldoc comments from the source has never worked, since exported symbols were asked for and none of those functions are exported to modules.
