There is some documentation about some of the logging concepts and
design. eg:
http://oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs-documentation.git;a=blob;f=design/xfs-delayed-logging-design.asciidoc
But the only way to learn about the actual structure of the log is to
read the code and use xfs_logprint to study the contents of the log.
Cheers,
