e65fe5a914 Kernel-doc: Convention: Use a "Return" section to describe return values
Non-void functions should describe their return values in their kernel-doc
comments. Currently, some don't, others do in various forms. For example:
   * Return the result.
   * Return: The result.
   * Returns the result.
   * Returns: the result.
   * Return Value: The result.
   * @return: the result.
   * This function returns the result.
   * It will return the result.

Defining a convention would improve consistency of kernel-doc comments. It
would also help scripts/kernel-doc identify the text describing the return
value of a function. Thus allowing additional checks on the comments, and
suitable highlighting in the generated docs (man pages, html, etc).

So, as a convention, use a section named "Return" to describe the return
value of a function.

eda603f6cd docbook: warn on unused doc entries
When you don't use !E or !I but only !F, then it's very easy to miss
including some functions, structs etc.  in documentation.  To help
finding which ones were missed, allow printing out the unused ones as
warnings.

For example, using this on mac80211 yields a lot of warnings like this:

  Warning: didn't use docs for DOC: mac80211 workqueue
  Warning: didn't use docs for ieee80211_max_queues
  Warning: didn't use docs for ieee80211_bss_change
  Warning: didn't use docs for ieee80211_bss_conf

when generating the documentation for it.

d2b34e20c1 documentation: update kernel-doc-nano-HOWTO information
Remove comments about function short descriptions not allowed to be on
multiple lines (that was fixed/changed recently).

Add comments that function "section header:" names need to be unique per
function/struct/union/typedef/enum.

6423133bde kernel-doc: allow multi-line declaration purpose descriptions
Allow the short description after symbol name and dash in a kernel-doc
comment to span multiple lines, e.g. like this:

	/**
	 * unmap_mapping_range - unmap the portion of all mmaps in the
	 *	specified address_space corresponding to the specified
	 *	page range in the underlying file.
	 * @mapping: the address space containing mmaps to be unmapped.
	 * ...
	 */

The short description ends with a parameter description, an empty line
or the end of the comment block.

52dc5aec9f kernel-doc: restrict syntax for private: and public:
scripts/kernel-doc can (incorrectly) delete struct members that are
surrounded by /* ...  */ <struct members> /* ...  */ if there is a /*
private: */ comment in there somewhere also.

Fix that by making the "/* private:" only allow whitespace between /* and
"private:", not anything/everything in the world.

This fixes some erroneous kernel-doc warnings that popped up while
processing include/linux/usb/composite.h.

28f4d75a61 documentation: how to use DOC: section blocks
Add info on how to use DOC: sections in kernel-doc.  DOC: sections enable
the addition of inline source file comments that are general in nature
instead of being specific to a function, struct, union, enum, or typedef.

0842b245a8 doc: document the kernel-doc conventions for kernel hackers
Provide documentation of the kernel-doc documentation conventions oriented
to kernel hackers.

Since I figure that there will be more people reading this
kernel-doc-nano-HOWTO.txt file who are kernel developers focused on the
rest of the kernel, than there will be readers of this file who are
documentation developers extracting that embedded kernel-doc
documentation, I have taken the liberty of making the new section added
here:

  How to format kernel-doc comments

the first section of the kernel-doc-nano-HOWTO.txt file.

This first section is intended to introduce, motivate and provide basic
usage of the kernel-doc mechanism for kernel hackers developing other
portions of the kernel.

In kernel-doc syntax, be a little flexible:  allow whitespace between
a function parameter name and the colon that must follow it, such as:
	@pdev : PCI device to unplug

(This allows lots of megaraid kernel-doc to work without tons of
editing.)

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
