The more or less simple question is:
Is the requirement for 32bit programs to support 64bit inodes the same 
as LFS(Large File Support)?

IOW if a programs was compiled with FILE_OFFSET_BITS=64 (if i remember 
that name correctly) should it work?
So that all programs compiled in the last several years in a halfway 
recent distribution should be able to cope with 64bit inodes?

The program i care about most is rsync and it appears to work correctly 
when i tested it with 2 hard-linked files (with an inode >2^32) and the 
option to preserve hard links. And "find" and "stat" also worked, 
otherwise i couldn't have found the file to test it with. ;-)
