395 | * The only exception is if we're on a platform with no 64-bit type at | |
396 | * all. | |
397 | * | |
398 | * Because we use read_longint() to get these off the wire, if you | |
399 | * transfer devices or hardlinks with dev or inum > 2**32 to a machine | |
400 | * with no 64-bit types then you will get an overflow error. Probably | |
401 | * not many people have that combination of machines, and you can | |
402 | * avoid it by not preserving hardlinks or not transferring device | |
403 | * nodes. It's not clear that any other behaviour is better. | |
404 | * | |
405 | * Note that if you transfer devices from a 64-bit-devt machine (say, | |
406 | * Solaris) to a 32-bit-devt machine (say, Linux-2.2/x86) then the | |
407 | * device numbers will be truncated. But it's a kind of silly thing | |
408 | * to do anyhow. | |
