Now I see why I couldn't find it. It's called "flush". Original patch
I had seen - back in 2005 http://lwn.net/Articles/165733/ - looks like
some variant of it made it into 2.6.19.

man mount days:

       flush  If set, the filesystem will try to flush to disk more early than
              normal.  Not set by default.

cheers,
