Hi All,

GlusterFS is now part of Coverity's scan program:


If you are interested in becoming a member of the project to set right 
false positives and provide modeling files, please let me know.

We have more than 600 issues to track. Your help in identifying false 
positives or actually addressing the issues by sending patches will be 
very welcome. I plan to submit weekly tarballs to keep our defect 
density in check.

Below is the defect report on GlusterFS 3.5qa1. Most of these seem to be 
coming from our recent activity on bd, zerofill and nfs.

Mohan, Santosh: Can you please look into these issues?
