This file can be used to adjust the score used to select which processes should
be killed in an out-of-memory situation. The oom_adj value is a characteristic
of the task's mm, so all threads that share an mm with pid will have the same
oom_adj value. A high value will increase the likelihood of this process being
killed by the oom-killer. Valid values are in the range -16 to +15 as
explained below and a special value of -17, which disables oom-killing
altogether for threads sharing pid's mm.
