[Ocfs2-tools-devel] [PATCH 0/3] 64bit journals

[Joel Becker]

This is the first cut of 64bit JBD2 journal support in ocfs2-tools.
fsck.ocfs2 can recover 64bit journals, debugfs can display them, and
mkfs can create them.

There's one big problem - fsck has never checked the journal compat
bits.  That means all previous versions of fsck.ocfs2 will happily read
a 64bit journal as a 32bit one and go nuts.  I think we're going to have
to add a filesystem incompat bit to handle this, unfortunately.

I wanted to get this stuff out to people to play with, though, so here
it is as it stands.

Future work involves adding the feature bit, failing
ocfs2_read_journal_superblock in the presence of unknown features,
teaching tunefs to turn on or off the 64bit journal and to allow resizes
appropriate to it.

Adding other JBD2 features will be independant work.
