individually.
[2015-07-20]
Editorial work on the introduction. Use of highlighted text to set of

LUDOC-296 protocol: Rearrange presentation to be more top-down
[2015-07-13]
Consistently use the file name 'struc_<bla>.txt' for content that
just has a structure and its description. Consistently refer to those
piece of content with the cross-reference label 'struct-<bla>'.
Mark each litteral text section(bounded by '----') with the
'[source,c]' tag so the HTML gets syntax highlighting.
[2015-07-12]
Flesh out some more of the rearrangement. Especially, try to push the
introduction of structuress to the place in the RPCs discussion where
it first occurs.

LUDOC-296 protocol: remove internal details from descriptions
[2015-07-09]
Tidy up some of the details in the removal of the implementation
details.
[2015-07-08]
Remove the internal implementation details from descriptions, in
particular for obd_import and obd_export. Some fields in those
structures will be useful in the future to describe the connection
state machine, but are commented out for now.
Remove the lustre_file_ids.txt file, since it largely duplicated
the file-id.txt file.

[2015-07-08]
This change moves all the content around, but does not alter it
much. The 'lustre_messages.txt' section is removed, since the RPCs are
introduced in a different way. The 'lustre_operations.txt' section is
renamed 'lustre_rpcs.txt'.

LUDOC-276 protocol: Document RPCs for setattr
[2015-06-09]
After Jinshan's second pass:
Section 7.1, page 36-37
Added description of lov_mds_md
Section 13.12, page 51
Command 101: LDLM_ENQUEUE - Enqueue a loack request
Lock Value Block discussion
Section 13.13, page 51
Command 1034: LDLM_CANCEL - Cancel a lock request
Added the new discussion of the LDLM_CANCEL.
Section 14.4, page 64-68
Updated the discussion of the 'setattr' for a 'truncate' with the
details about the LDLM_CANCEL. Updated figures.
[2015-06-04]
Updates addressing Doug's comments. In particular, clarify how the
MDS_REINT structs are organized, and the constraints placed on the
interpretation of their fields in order to accommodate swabbing
correctly. Also, break the 'mdt_body' struct out into its own section,
in 'mdt_structs.txt', so that it does not seem to be another variant
of the 'mds_rec_reint'. Fix a minor markup issue in
'ost_setattr_structs.txt'.
[2015-05-31]
First round update in response to review:
Especially addressing defects in 'setattr.txt'.
Figures and text discuss RPCs that implement 'setattr'. There is a new
top-level file called 'extract_setattr.txt' that include just the new
content. It can be compiled with
asciidoc extract_setattr.txt
for the HTML, and
a2x -f pdf --fop extract_setattr.txt
for the PDF. The extract_setattr.pdf that results is also organized in
a more top-down fashion than the 'protocol.pdf'. We are still
considering which oreder of presentation (versus bottom-up) is
preferable. The figures each involves one of two kinds of thing:
either a UML-style sequence diagram (files ending in '_rpcs.png'), or
an RPC packet structure diagram.
The previously existing files data_types.txt,
file_system_operations.txt, ldlm.txt, lustre_messages.txt,
lustre_operations.txt, and protocol.txt all had very minor edits that
simply bring in the new content in the other files. The one excetion
is that previous content on LDLM has been improved and extended.
The setattr.txt file has the new content discussing 'setattr' in terms
of the RPCs that are exchanged. The remaining new files each
introduces one small piece of the new content relating to one specfic
detail, each.

LUDOC-270 protocol: Update the outline and add support files
This patch modifies the outline to the document:
- Orgainizing the presentation a little better
- Removing empty sections until they are ready to be included
- Breaking main topics out into separate files
The organization is bottom-up in that it starts with a Dtat Types
Section, builds on that by showing how messages are structured, then
addresses how the Lustre operations use those messages, and finally
how file system activitiy uses Lustre oparations to carry out its
activities.

LUDOC-270 protocol: Add a 'basement' dir with support files
The basement has been added as a place to put content that may be
interesting to the community, but is nevertheless not directly a part
of the documentation for this project. It has, for instance, a catalog
of structures and other definitions that relate to how Lustre messages
are formed. Those files (see the README) make a direct reference to
the Lustre sources, and were the raw material for the content that
will be added shortly.

LUDOC-266 protocol: Initial content for new repository
Initial content for the new 'protocol' repository.
The primary 'source' content in this repository is a collection of
text files ('*.txt') in the 'asciidoc' format, augmented with some
figures constructed with 'graphviz' ('*.gv'). 'asciidoc' will
produce '.html', '.pdf', and '.xml' (DocBook) files. 'graphviz'
('dot' actually) will produce '.png' files. The '.gitignore' file
lists these derived file extensions so the 'compiled' results will
not be a part of the repository contents, but instead will be build
afresh when needed.
In the 'figures' directory there is one '.gv' file (mkdir1.gv) that attempts to
capture some ideas about one state machine. It is an early effort at
this point.
The Makefile generates two commonly desirable output formats from
the source. These are .html and .pdf.
