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