418 | * ino_t and dev_t internally, even if this platform does not | |
419 | * allow files to have 64-bit inums. That's because the | |
420 | * receiver needs to find duplicate (dev,ino) tuples to detect | |
421 | * hardlinks, and it might have files coming from a platform | |
422 | * that has 64-bit inums. | |
423 | * | |
424 | * The only exception is if we're on a platform with no 64-bit type at | |
425 | * all. | |
426 | * | |
427 | * Because we use read_longint() to get these off the wire, if you | |
428 | * transfer devices or hardlinks with dev or inum > 2**32 to a machine | |
429 | * with no 64-bit types then you will get an overflow error. Probably | |
430 | * not many people have that combination of machines, and you can | |
431 | * avoid it by not preserving hardlinks or not transferring device | |
432 | * nodes. It's not clear that any other behaviour is better. | |
433 | * | |
434 | * Note that if you transfer devices from a 64-bit-devt machine (say, | |
435 | * Solaris) to a 32-bit-devt machine (say, Linux-2.2/x86) then the | |
