Re: [Patch BUGFIX] kcore: fix its wrong size on x86_64

Hi Amerigo,

The wrong number I mean is 131941393240064.

So do you think
[root@test3 ~]# ls -l /proc/kcore
-r-------- 1 root root 131941393240064 Jun 15 13:39 /proc/kcore

is better than

[taoma@test2 ~]$ ll /proc/kcore
-r-------- 1 root root 281474974617600 Jun 15 15:20 /proc/kcore

I don't think so.

Actually the right result should look like

[root@test8 ~]# ls -l /proc/kcore
-r-------- 1 root root 5301604352 Jun 15 13:35 /proc/kcore

And with your patch I can't get this number.

Hi Amerigo,
Just patched my kernel and tested.
The bad news is that although the number is changed, but it isn't right either.

Thanks for testing.

What do you mean by saying it isn't right? You think it is wrong only because
it is more than phy mem size?

Again, the document of /proc/kcore is wrong, it _can_ be more than phy mem size.
