Older data? It is newer data. 1. write data first, and then trigger checkpoint, after checkpoint, data will become checkpointed one, for such case we can only collapse w/ data copying. 2. write data (data is non-checkpointed if there is no following checkpoint), then we can collapse w/ metadata update. _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
