Hello,
we are figuring out upstream how to eventually get rid of maintaing three code bases of ext2, ext3, and ext4 in parallel. These days ext4 kernel driver is able to handle both ext2 and ext3 filesystems in a backward compatible manner - i.e., you can mount, access, modify the filesystem with ext4 driver and then still be able to use it with the old ext2 driver. So I'd think that we could try changing config of our kernel in Factory so that ext4 driver is used for ext2 filesystem and see whether something breaks or not.
Do people have any opinion on this?
Wouldn't it be a safest path to replace the use cases of ext2 with ext_3_? It's way more mature than ext4, and presumably people have already been using ext3 to mount ext2 partitions for years. As you didn't mention a plan to drop the ext3 driver, I'd use it for ext2. IMHO it only makes sense to use the ext4 driver for ext2 partitions if we plan to drop the ext2 _and_ ext3 drivers, and use the ext4 driver for all three partition types. Just my two I-don't-know-a-thing-about-file-systems cents. -- Jean Delvare Suse L3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
