295 | * allow files to have 64-bit inums. That's because the | |
296 | * receiver needs to find duplicate (dev,ino) tuples to detect | |
297 | * hardlinks, and it might have files coming from a platform | |
298 | * that has 64-bit inums. | |
299 | * | |
300 | * The only exception is if we're on a platform with no 64-bit type at | |
301 | * all. | |
302 | * | |
303 | * Because we use read_longint() to get these off the wire, if you | |
304 | * transfer devices or hardlinks with dev or inum > 2**32 to a machine | |
305 | * with no 64-bit types then you will get an overflow error. Probably | |
306 | * not many people have that combination of machines, and you can | |
307 | * avoid it by not preserving hardlinks or not transferring device | |
308 | * nodes. It's not clear that any other behaviour is better. | |
309 | * | |
310 | * Note that if you transfer devices from a 64-bit-devt machine (say, | |
311 | * Solaris) to a 32-bit-devt machine (say, Linux-2.2/x86) then the | |
312 | * device numbers will be truncated. But it's a kind of silly thing | |

315 | * FIXME: In future, we should probable split the device number into | |
316 | * major/minor, and transfer the two parts as 32-bit ints. That gives | |
317 | * you somewhat more of a chance that they'll come from a big machine | |
318 | * to a little one in a useful way. | |
