Comment 26 for bug 1365874

I would like to test this configuration in my laptop with a slow rotational disk + a small SSD: https://raid6.com.au/posts/fs_ext4_external_journal_caveats/

But, if I understood correctly, I need to configure journal_async_commit for it to be reliable, and that option automatically enables journal_checksum, that it's not available in the current e2fsprogs version that ubuntu 16.04 has...am I missing something?

I also think that what Simon comments about the SRU is quite sensible, but if getting a SRU is too hard, would it make sense to open a ticket requesting a backport from bionic to xenial?
