[newbie] Kernel SOurce

[Manaxus]

Hello,   I am trying to work with version 9.1 with respect to device driver development and I chose to install kernel source upon installation but I cannot find ANY .c file. The headers are there, but none of the .c’s.   When I searched I was logged in as root user, searching from the / directory and I issued the following command: Find –name swapfile.c –mount   This is the same for all .c files.   Can anyone enlighten me as to where the source code is at?   Thanks.
