Hi!

Can a single call to the a disk driver request more than 64 KB of data,
i.e., can the buf structure hold more than 64 KB of data if the amount of 
memory is available (buf.b_data points to a memory region > 64 KB)?

(For example if data is stored mostly contiguous on disk and we are able
to read 128 KB contiguously)

Thank you for your help,
