ctr : Fix for heating of files during promotion/demotion
This fix will solve the heating of the files during the promotion or demotion. Promotion: ~~~~~~~~~ When a file gets promoted it get the current time stamp during creation only, but following writes or reads during the migration wont heat the file. Demotion: ~~~~~~~~ When a file gets demoted it get the wind/unwind time stamp is set to zero. The following writes or reads during the migration wont heat the file. What is remaining ? ~~~~~~~~~~~~~~~~~ Bug 1209129 ( https://bugzilla.redhat.com/show_bug.cgi?id=1209129 ) Inspite of this fix there is still a issue remaining, i.e the heat of the file is not keep intact during a internal rebalance activity i.e a rebalance within a tier.
