ocfs2: Allow for debugging of transaction extends
The nastiest cases of transaction extends are also the rarest. We can expose them more quickly at the expense of performance by going straight to the journal_restart() in ocfs2_extend_trans(). Wrap things in OCFS2_DEBUG_FS so that we only do this when "expensive debugging" is turned on. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
