No, actually, a metadata-only sync would *increase* the chance of causing problems over not using anything at all. The necessary operation is to *prevent* writing the metadata until the data has been written.

Ext4 filesystem hits Android, no need to fear data loss (ars technica) Posted Jan 1, 2011 19:22 UTC (Sat) by butlerm (subscriber, #13312) [Link] The necessary operation is to *prevent* writing the metadata until the data has been written.That can lead to severe performance issues, unless you implement some sort of multiversion concurrency (a la BSD style "soft updates") on all your metadata. There are better ways.
