[lvm-devel] [PATCH lvconvert 5/11] Don't insert temporary layer for corelog mirror

[Jun'ichi Nomura]

lvconvert inserts a temporary layer so that it can sync newly added
mirrors while keeping the original mirror in-sync.
However, LVM2 manages in-sync status for corelog mirror by
the global _mirror_in_sync variable.
So the insertion just duplicates the sync effort.

If the original mirror is corelog, we can just add mimage LV to it
and restart sync.

Thanks,
