Assuming there is an fd opened on these files always and if
cluster.force-migration is set to off, there will be no migration. However,
we can force migration (even on files with open fds) by setting
cluster.force-migration to on.

Would this patch affect tiering as well ?
Do we need to worry about tiering anymore ?
