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.
