Just a minor correction: this is not a raw partition, but a buffered blockdevice. If you want a real rawdevice (where sync is a noop because all IO goes synchronously to disk) you need to bind a character raw device to the block device first using the raw util. >From a quick look sync_buffers() [which implements fsync on block devices] has not changed significantly between 2.2 and 2.4 and uses the same algorithm. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
