zfs discuss - Mar 2008 - reviewers needed for paper on zfs on-disk structure walk

Hi,
I am (hoping) to present a paper at osdevcon in Prague in June.  I have 
a draft of the paper and
am looking for a couple of people to review it.  I am interested to know 
the following:
1. Is it understandable?
2. Is it technically correct?
3. Any comments/suggestions to make it better?

The paper starts at the active uberblock on the disk, and walks the data 
structures on disk
to find the data for a given file.  It uses a modified mdb and modified 
zdb, along with an mdb
dmod.  It is not specifically aimed at system administrators, but rather 
tries to give people
better insight as to where and how data is located in a ZFS file system.

So, anyone interested in reviewing this?  If so, let me know via email 
and I''ll send
you a copy.  Also, if you want the modified mdb/zdb and the dmod, let me 
know that
as well.

thanks much,
max
