I have my doubts about 5 minutes of writes outstanding, unless someone has tuned it that way; or possibly a case like the file still being open and overwritten (where the metadata doesn't change until closed). ext4(5) says a default of 5 seconds for the "commit=nrsec" option, although I'm not 100% certain if that tells the entire story. Writing a new file, closing it, then renaming over the old file should, I believe, trigger a metadata write to the journal within the commit time (i.e. 5s by default), which should be after the data is written in the default data=ordered mode. That's how I interpret the documentation, anyway; I'm not an absolute expert on the subtle inner workings of ext4.
