283 | * ino_t and dev_t internally, even if this platform does not | |
284 | * allow files to have 64-bit inums. That's because the | |
285 | * receiver needs to find duplicate (dev,ino) tuples to detect | |
286 | * hardlinks, and it might have files coming from a platform | |
287 | * that has 64-bit inums. | |
288 | * | |
289 | * The only exception is if we're on a platform with no 64-bit type at | |
290 | * all. | |
291 | * | |
292 | * Because we use read_longint() to get these off the wire, if you | |
293 | * transfer devices or hardlinks with dev or inum > 2**32 to a machine | |
294 | * with no 64-bit types then you will get an overflow error. Probably | |
295 | * not many people have that combination of machines, and you can | |
296 | * avoid it by not preserving hardlinks or not transferring device | |
297 | * nodes. It's not clear that any other behaviour is better. | |
298 | * | |
299 | * Note that if you transfer devices from a 64-bit-devt machine (say, | |
300 | * Solaris) to a 32-bit-devt machine (say, Linux-2.2/x86) then the | |
301 | * device numbers will be truncated. But it's a kind of silly thing | |
302 | * to do anyhow. | |
b9df3bf2 MP |
303 | * |
304 | * FIXME: In future, we should probable split the device number into | |
305 | * major/minor, and transfer the two parts as 32-bit ints. That gives | |
306 | * you somewhat more of a chance that they'll come from a big machine | |
307 | * to a little one in a useful way. | |
