Hi, I would like to announce the first public version of my timeout based user-space low memory killer daemon (tbulmkd). It is based on idea that user-space applications can be divided into two classes, foreground and background ones. Foreground processes are visible in graphical user interface (GUI) and therefore shouldn't be terminated first when memory usage gets too high. OTOH background processes are no longer visible in GUI and are pro-actively being killed to keep overall memory usage smaller. Actual daemon implementation is heavily based on the user-space low memory killer daemon (ulmkd) from Anton Vorontsov (http://thread.gmane.org/gmane.linux.kernel.mm/84302). The program is available at: https://github.com/bzolnier/tbulmkd kernel/add-tbulmkd-entries.patch needs to be applied to the kernel that would be used with tbulmkd. It adds /proc/$pid/activity and /proc/$pid/activity_time files. Write '0' to activity file to mark the process as background one and '1' (the default value) to mark it as foreground one. Please note that this interface is just for a demonstration of tbulmkd functionality and will be changed in the future.
