The functions, code excerpts and comments discussed below here are from mm/oom_kill.c unless otherwise noted. It is the job of the linux 'oom killer' to sacrifice one or more processes in order to free up memory for the system when all else fails. It will also kill any process sharing the same mm_struct as the selected process, for obvious reasons.
