Not at present AFAIK, and it can't really be done.  Imagine the case of
holding a file open but unlinked: according to fsck, that is an error,
and it (fsck) will blow away or relink the file.  But for a live
system, it is a perfectly normal condition.

You'd have to fix fsck to recognize what things that are errors for
unmounted filesystems are not errors for live filesystems and run fsck
with this (hypothetical) -live flag, at a minimum.  Given that, it
might be useful, but even then, you run the risk of fsck destroying
something the kernel is actively using.
