I really like this idea. Can people please try out the attached patch?

Please note, it contains a couple of things that need not be there in
the final version.

Note, there is also a reiserfs fix in here because we can call
f_op->fsync on a directory and without this fix it will BUG!  Chris,
perhaps you can suggest a better fix?


Linus, one more thing --- the first argument to ->fsync is struct file*
and nothing uses it, I'd like to blow it away or would you prefer we
wait to 2.5.x as its essentially and API change and will break XFS,
JFS, etc.
