| The lowmemorykiller driver lets user-space specify a set of memory thresholds |
| where processes with a range of oom_adj values will get killed. Specify the |
| minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the |
| number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both |
| files take a comma separated list of numbers in ascending order. |
| |
| For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and |
| "1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill processes |
| with a oom_adj value of 8 or higher when the free memory drops below 4096 pages |
| and kill processes with a oom_adj value of 0 or higher when the free memory |
| drops below 1024 pages. |
| |
| The driver considers memory used for caches to be free, but if a large |
| percentage of the cached memory is locked this can be very inaccurate |
| and processes may not get killed until the normal oom killer is triggered. |
