Long time ago (before 2.6.32, or so) ->write_super() was used by vfs
for sync(). However, starting from .32 (or so) it isn't, so I have
written a reiser4 implementation of ->sync_fs() for this purpose.

It seems that nowadays reiser4_sync_super is completely defuncted
(please, check) and is not needed any more. Reiser4 has its own
periodic writeout means (ktxnmgrd). ReiserFS (v3) didn't have this one.

So, I think, remove...

Thanks,
Edward.
