Such filesystems require frequent writes and change their internal state often. This could be alleviated by COWing the filesystem somehow and flushing writes when you're finished. But the modifications will be lost if crashes occur. The filesystem structures will still change a lot and require big writes to update it. Really, why don't you try a more suitable fs for your pendrive, one that changes itself less than usual fs's? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
