-/* Starting from protocol version 26, we always use 64-bit

- * allow files to have 64-bit inums. That's because the
- * receiver needs to find duplicate (dev,ino) tuples to detect
- * hardlinks, and it might have files coming from a platform
- * that has 64-bit inums.
- *
- * The only exception is if we're on a platform with no 64-bit type at
- * all.
- *
- * Because we use read_longint() to get these off the wire, if you
- * transfer devices or hardlinks with dev or inum > 2**32 to a machine
- * with no 64-bit types then you will get an overflow error. Probably
- * not many people have that combination of machines, and you can
- * avoid it by not preserving hardlinks or not transferring device
- * nodes. It's not clear that any other behaviour is better.
- *
- * Note that if you transfer devices from a 64-bit-devt machine (say,
- * Solaris) to a 32-bit-devt machine (say, Linux-2.2/x86) then the
- * device numbers will be truncated. But it's a kind of silly thing
- * to do anyhow.
- *
- * FIXME: I don't think the code in flist.c has ever worked on a system
- * where dev_t is a struct.
