I must confess I'm so far behind on following these patches that I don't know the answer to this, so.. Does this patch compare the *ending* block number when checking for 28-bit LBA, or the *starting* block number? It's the *ending* block number that should be used, because some drives don't deal well with boundary crossings. Cheers
