NBD actually exports a flag for rotational devices; it's defined in nbd.h in the NBD userland source as #define NBD_FLAG_ROTATIONAL (1 << 4) /* Use elevator algorithm - rotational media */ which is passed in the same flags field which also contains the NBD_FLAG_SEND_FLUSH and NBD_FLAG_SEND_FUA flags. Perhaps we might want to look at that flag and set the device to rotational if it is specified?
Yes, that sounds good. Can you send a patch?
