[Ocfs2-devel] Any other reading about DLM?

[Eric Ren]

Hi Joseph and all,

In order to learn about DLM, I got [1][2][3] besides source code in 
fs/dlm and fs/ocfs2/dlm.
Among them, [1][2] are for fs/dlm, and [3] is for fs/ocfs2/dlm. But most 
parts of [3] is not complete yet.

[1] http://opendlm.sourceforge.net/cvsmirror/opendlm/docs/dlmbook_final.pdf
[2] http://people.redhat.com/ccaulfie/docs/rhdlmbook.pdf
[3] https://oss.oracle.com/~smushran/ocfs2_dlm_design_draft.pdf

So, I'm wondering if anyone has a complete [3]? Or Any other reading 
like docs, notes and blogs about DLM?
Thanks in advance;-)

Eric
