Re: [PATCH] A new entry for /proc

[Mauricio Lin <mauriciolin@gmail.com>]

Hi,

Just some explanation about the mistake.

I have put cat /proc/pid/status instead of /proc/pid/smaps.

So I was testing the /proc/pid/status and not the /proc/pid/smaps.

Now I am testing with /proc/pid/smaps and the values are showing that
the old one is faster than the new one. So I will keep using the old
smaps version.

Any suggestion???

BR,

Mauricio Lin.
