While Xavi replies to this mail, here are my inputs. I am not
very familiar with the old code because I didn't get a chance to look at
them deeply. But I do know about dfc. All the code of disperse volume is
in 'xlators/cluster/ec'. At the moment EC is using synchronization
similar to afr for now, so dfc is not in upstream yet. Heal in ec is
also changed similar to afr and is done automatically by glustershd, so
the functionality of 'heal' I think is implemented in
ec-heal.c(Healing), ec-heald.c (automatic healing part). Did I get that
