It would be difficult to make that generic since the errors and the
resulting actions which can be taken vary from fs to fs. The main reason
that I didn't do it at this point in time is that the GFS2 error
handling needs revising anyway, and once that is done (probably with an
errors= option similar to ext2/3/4) it might be possible to think about
LED support for that,

Steve.
