The following series of patches implement API call needed to handle 64-bit block numbers. Im concentrating mainly in providing the API call first and if the interfaces are sane, we can go ahead and start using them in the rest of libext2fs and the user space programs. It also introduces the changes needed in order to for mke2fs to support larger that 32-bit blocknr devices. Bitmap dependencies are commented with "/* FIXME-64 */" to make them easy to find and replace with the new interface. -JRS -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
