   It is why I'm asking, or even begging, for help from you or other person,
 who understand SU/SU+J well for help to make it properly!

  Which codepaths in ffs_softdep.c are used with SU/SU+J? For example,
 bwrite() is used in softdep_process_journal() or
 clear_unlinked_inodedep()-- I see here contradiction with statement,
 that brwite() is only used WITHOUT SU and SU+J. But it seems, that I
 don't understand this code at all.
