[opensuse-kernel] Use ext4 kernel driver for ext3 filesystems?
Hello, so it has been about 1 year since openSUSE uses ext4 kernel driver for ext2 filesystems. I haven't heard any complaints so I feel it's time to do the same for ext3 as well. Fedora actually uses this setting for over an year already so it's not like we are going to use something heavily experimental. I'd just add that this transition is desirable as ext3 is slowly being deprecated upstream in favor of ext4 (so that we can get rid of similar code bases). Anyone has any objections?

I think that I had one machine that silently added some ext3 options to my ext2 filesystem on mount and it was no longer mountable as ext2 afterwards. We should make sure this doesn't happen accidentally. (The device was an USB stick I use as rootfs for an embedded device. I plugged it into my opensuse box for copying files to / from it and afterwards the embedded box did not boot anymore with rootfstype=ext2. I did not bother debugging this but just switched to rootfstype=ext3 for the embedded device :-) -- Stefan Seyfried "If your lighter runs out of fluid or flint and stops making fire, and you can't be bothered to figure out about lighter fluid or flint, that is not Zippo's fault." -- bkw -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

I did not bother debugging this but just switched to rootfstype=ext3 for the embedded device :-) Strange :-) Anyway, now I tested that when I run full xfstest run on an ext3 filesystem mounted using ext4, it is then still mountable using old ext3 driver. So it looks OK.
So I've disabled ext3 in master branch in all configs... Honza -- Jan Kara <jack@suse.cz> SUSE Labs, CR -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
