    ocfs2: invalidate dentry if its dentry_lock isn't initialized
    
    In mainline commit a5a0a630922a2f6a774b6dac19f70cb5abd86bb0, when
    ocfs2_attach_dentry_lock fails, we call an extra iput and reset
    dentry->d_fsdata to NULL. This resolve a bug, but it isn't
    completed and the dentry is still there. When we want to use
    it again, ocfs2_dentry_revalidate doesn't catch it and return
    true. That make future ocfs2_dentry_lock panic out.
    One bug is http://oss.oracle.com/bugzilla/show_bug.cgi?id=1162.
    
    The resolution is to add a check for dentry->d_fsdata in
    revalidate process and return false if dentry->d_fsdata is NULL,
    so that a new ocfs2_lookup will be called again.

    ocfs2/dlm: Wait on lockres instead of erroring cancel requests
    
    In case a downconvert is queued, and a flock receives a signal,
    BUG_ON(lockres->l_action != OCFS2_AST_INVALID) is triggered
    because a lock cancel triggers a dlmunlock while an AST is
    scheduled.
    
    To avoid this, allow a LKM_CANCEL to pass through, and let it
    wait on __dlm_wait_on_lockres().

    ocfs2: __ocfs2_abort() should not enable panic for local mounts
    
    In a clustered setup, we have to panic the box on journal abort. This is
    because we don't have the facility to go hard readonly. With hard ro, another
    node would detect node failure and initiate recovery.
    
    Having said that, we shouldn't force panic if the volume is mounted locally.
    This patch defers the handling to the mount option, errors.
