[Ocfs2-tools-devel] [PATCH] Make tunefs.ocfs2 understand all journal options.

It is not simply a case of toggling a feature in the journal superblock.
That bit affects the format of the journal meta-data. In the least we'll
need to safely re-init the journal.

Is there a need for this? The only case I can think of is if a user wants
to resize from < 16T to > 16T.
