There are behavioural requirements on the seq_file next() function in terms of how it updates *pos at end-of-file, and these are now enforced by a warning. I was recently attempting to justify the reason this was needed, and couldn't remember the details, and didn't find them in the documentation. So I re-read the code until I understood it again, and updated the documentation to match. I also enhanced the text about SEQ_START_TOKEN as it seemed potentially misleading.

The command-line parameters "dyndbg" and "async_probe" are not parameters for kernel/module.c but instead they are for the module that is being loaded. Try to make that distinction in the help text. OTOH, "module.sig_enforce" is handled as a parameter of kernel/module.c so "module." is correct for it. Signed-off-by:

Following the structure used in sysctl/kernel.rst, this updates abi.rst to use ReStructured Text more fully and updates the entries to match current kernels: * the list of files is now the table of contents; * links are used to point to other documentation and other sections; * all the existing entries are no longer present, so this removes them; * document vsyscall32. Mentions of the kernel version are dropped. Since the document is entirely rewritten, I've replaced the copyright statement. Signed-off-by: -

Subroutine dump_struct uses type attributes to check if the struct syntax is valid. Then, it removes all attributes before using it for output. `____cacheline_aligned` is an attribute that is not included in both steps. Add it, since it is used by kernel structs. Based on previous patch to add ____cacheline_aligned_in_smp. Motivated by patches to reorder this attribute to before the variable name. Whilst we could do that in all cases, that would be a massive change and it is more common in the kernel to place this particular attribute after the variable name. A quick grep suggests approximately 400 instances of which 341 have this attribute just before a semicolon and hence after the variable name. Signed-off-by:

Cross-referencing to other documentation pages is possible using the :doc:`doc-file` directive from Sphinx. Add automatic markup for references to other documentation pages in the format Documentation/subfolder/doc-file.rst (the extension being optional). This requires that the path be passed all the way from the Documentation folder, which can be longer than passing a relative path through the :doc: directive, but avoids the markup, making the text cleaner when read in plain text.
