I can't confirm that this works - we still have the problems with hanging
sessions with latest glusterfs from git (cloned today) - is the patch already
applied to current git?

There are three different branches now

origin/release-2.0  - For 2.0.x releases
origin/release-3.0  - For 3.0.x releases
master - Upcoming 3.x releases

Now if you are using "master" branch in git you are bound to have problems as it not tested.  If you are using "release-3.0" branch please send us your log files too.

Earlier suggested patch will be included in the 3.0.3 release ie. release-3.0 branch already has the patch.
