Parent pointers

[Allison Henderson <allison.henderson@oracle.com>]

Hi all,

I've been doing some digging on adding parent pointers to xfs and wanted 
to send a note to folks here to get peoples opinions on it.  I got in 
touch with Brian Foster not too long ago and he had some code partially 
done from about a year or so ago (looks like it has patches from Dave 
Chinner and Mark Tinguely as well).  So I am hoping to be able to use 
what we have so far to create something updated and finished out.  I am 
still pretty new to the xfs code, so at the moment I am still just going 
through old discussion threads, and reviewing the patches.  But for the 
most part I just wanted to see what people thought and get everyone on 
board with the idea.  Suggestions and feedback are much appreciated. 
Thank you!!
