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. Any particular process leader may be immunized against the oom killer if the value of its /proc//oomadj is set to the constant OOM_DISABLE (currently defined as -17).
The function which does the actual scoring of a process in the effort to find the best candidate for elimination is called badness(), which results from the following call chain:
_alloc_pages -> out_of_memory() -> select_bad_process() -> badness()
The comments to badness() pretty well speak for themselves:

Many computer users have an insatiable appetite to deepen their understanding of computer operating systems and computer software. Linux users are no different in that respect. At the same time as developing a huge range of open source software, the Linux community fortunately has also written a vast range of documentation in the form of books, guides, tutorials, HOWTOs, man pages, and other help to aid the learning process. Some of this documentation is intended specifically for a newcomer to Linux, or those that are seeking to move away from a proprietary world and embrace freedom.
There are literally thousands of Linux books which are available to purchase from any good (online) book shop.

This article should be read in conjunction with our previous article on free Linux books, entitled 20 of the Best Free Linux Books."
