[Ocfs2-tools-devel] [PATCH 8/9] libocfs2: Support 64bit journals.

[Joel Becker]

libocfs2 is ensured to check the journal feature bits before continuing
via the COMPAT_JBD2_SB filesystem feature.  fsck.ocfs2 can replay and
recover 64bit journals.  tunefs.ocfs2 copies journal feature bits when
creating new slots.  We are now safe to mark the feature bit supported.
