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

[Tao Ma]

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.

Regards,
Tao
