.. so work with an extent-based filesystem instead.

16k blocks are total idiocy. If this wasn't about a "support legacy customers", I think the whole patch-series has been a total waste of time.

Admittedly, extent-based might not be a particularly bad answer at least to the I/O side of the equation...

I do feel larger blocksizes continue to make sense in general though. Packet writing on CD/DVD is a problem already today since the hardware needs 32K or 64K blocks and I'd expect to see more of these and similiar situations when flash gets (even) more popular which it sort of inevitably is going to be.
