That's not a place where I keep my code (and has never been :-)
ftp://ftp.sw.com.sg/pub/Linux/people/saw/kernel/user_beancounter/UserBeancounter.html
is the right place (but it has some availability problems :-(
As for memory management, it provides a simple variant of service level
support for
- in-core memory (in opposite to swap)
- total "virtual" memory.
The latter ends up in accounting of how much memory is consumed by each
subject of accounting, and an OOM-killer.
OOM-killer takes into account guarantees given to the subject and selects the
victim. In the patch on the ftp site the selection code is very simple and
taken from some old OOM patches.
BTW, I've redone memory accounting code to significantly improve it's
performance (or, to say in other words, to reduce the performance penalty
imposed by the accounting). But this new code isn't integrated to the
complete user beancounter patch.
Best regards
Andrey
