    o2cb.init: Load dlmfs for user stacks when supported
    
    If dlmfs supports user stacks, load and mount it at startup.
    This is gated by the 'stackglue' capability.  ocfs2_dlmfs reports this
    as a module parameter named 'capabilities'.  If ocfs2_dlmfs is built-in
    or loaded, this will appear at
    /sys/module/ocfs2_dlmfs/parameter/capabilities.  If it is not loaded, we
    can find it via modinfo.

    libo2dlm: Add support for BASTs
    
    ocfs2_dlmfs can now notify userspace of BASTs via poll(2) or select(2).
    We need a way for libo2dlm users to actually access this information.
    
    This change introduces two new functions.  The first,
    o2dlm_lock_with_bast(), is exactly like o2dlm_lock() except that it
    takes a BAST function and returns a file descriptor to poll on.  When
    that file descriptor signals data is ready, the program calls the second
    new function, o2dlm_process_bast().  This will fire off the appropriate
    BAST.
    
    If dlmfs isn't BAST capable, we'll get an error.

    libo2dlm: Provide capability queries
    
    ocfs2_dlmfs can now report added capabilities via a module parameter.
    libo2dlm now can query them before trying to use them.
    
    The two known capabilities at this time are 'bast' and 'stackglue'.

    ocfs2_journal_check_available_features(): Never allow FEATURE_COMPAT_CHECKSUM
    
    ocfs2 will never use jbd2 checksums.  If a jbd2 checksum fails, the
    transaction is not replayed.  This means that some parts of the
    transaction may have checkpointed while other parts have not.  This
    inconsistent state requires fsck to repair.  ocfs2, being clustered,
    can't tolerate that situation.  Instead, ocfs2 prefers to replay the
    journal.  This allows the cluster to remain running.  Using the METAECC
    feature allows ocfs2 to detect and isolate any corrupted blocks.
