Hmmm, didn't Christoph fix these inode number warnings by changing
the format specifier to PRIU64, not by adding casts? bs_ino is
defined as:

	__u64		bs_ino;

So PRIu64 is the right thing to do, isn't it?

Either way would work, but being consistent would be good. ;)

Same for al the be64_to_cpu() functions - their return type is
__u64, too.

That format specifier is wrong - it is %lld. Should be %llu, or
PRIu64 as previously mentioned without the cast.

Cheers,
