[Crash-utility] How to find core utlility implementation (source code) file in Linux kernel ?

[VL Chowdary]

Hi,
This is VL Chowdary, a software engineer in Bangalore,India.I am currently
working on a project that deals with "Creation of Postmortem data log file
on Linux platform".
The project is on Fedora 12 with Kernel2.6.31.5 version.
 For that i need following things.
       1. Find the location of core utility in the kernel.
       2. Find  the source file that consists of actual implementation of
the core utility (On Fedora's kernel 2.6.31.5)
       3. Based on that i want to implement a core file with my own project
requirements.
       4. Build the kernel with the above implemented corefile replacing the
existing one.

                                                     I went through many
documents and they were saying that core file generated location is in :
         /proc/sys/kernel.
                              Is it correct?.
I couldn't get the source file that contains the implementation of core
utility.
Please help in the project for further proceedings.
Advance thanks to all repliers.

Thank you,
vlc
