Playing with the Linux Kernel: Process Segments

Interesting experimental programs explore process segments...
Under Linux, a process can execute in two modes - user mode and kernel mode. A process usually executes in user mode, but can switch to kernel mode by making system calls. When a process makes a system call, the kernel takes control and does the requested service on behalf of the process. The process is said to be running in kernel mode during this time. When a process is running in user mode, it is said to be "in userland" and when it is running in kernel mode it is said to be "in kernel space". We will first have a look at how the process segments are dealt with in userland and then take a look at the bookkeeping on process segments done in kernel space.
