CentOS - May 2011 - Where is the Centos Linux 5.5 kernel syscall handler for mmap?

Good evening, We are using Centos Linux Release 5.5 x86_32. We wondering where
the kernel syscall handler for mmap in Centos Linux 5.5 distribution is
located(for example /usr/xxx/....)? Would any programmers or operating system
administrators have this information? Thank you.

Hello Frank.

You could try to grep the source code if you have some idea 
of the function name you are looking for.

Hi. Sorry for the late reply, but I did not get the message 
that was archived.

I stumbled upon it here:

http://osdir.com/ml/centos/2011-05/msg01193.html

All I got was this message:

I am out of the office until 06/11/2011.

I will be out of the office starting 5/27/2011 and will not 
return until 6/12/2011. I will respond to your message when 
I return.

Note: This is an automated response to your message "CentOS 
Digest, Vol 76, Issue 28" sent on 5/28/2011 9:00:02 AM.

This is the only notification you will receive while this 
person is away.

In response to your question:

"Thank you for your suggestion about doing a grep of the 
source code. We found mmap.S in 
../sysdeps/unix/sysv/linux/i386. We looked in mmap.S and 
found a lot of assembly code. Could you please tell us if 
any of the assembly code call the kernel syscall handler 
for mmap.s?

Also, we ran make for the kernel Makefile and we obtained 
the following result shown below. Could you please suggest 
us how to fix the kernel Makeconfig so that it skips over 
libc_pic.os? Thank you for your help."

May I suggest you join the LKML?

http://www.kernel.org/pub/linux/docs/lkml/

I'm sure they are alot more knowledgeable concerning things 
like tweaking the internals of the Linux kernel.

HTH

Kind Regards,

Keith Roberts
