名称描述
oom_cpuset_eligiblem_cpuset_eligible() - check task eligiblity for kill*@start: task struct of which task to consider*@oc: pointer to struct oom_control* Task eligibility is determined by whether or not a candidate task, @tsk,* shares the same mempolicy nodes as current if
constrained_allocDetermine the type of allocation constraint.
oom_evaluate_task
select_bad_processSimple selection loop. We choose the process with the highest number of* 'points'. In case scan was aborted, oc->chosen is set to -1.
dump_task
dump_tasksdump_tasks - dump current memory state of all system tasks*@oc: pointer to struct oom_control* Dumps the current memory state of all eligible tasks. Tasks not in the same* memcg, not in the same cpuset, or bound to a disjoint set of mempolicy nodes
dump_header
out_of_memory_of_memory - kill the "best" process when we run out of memory*@oc: pointer to struct oom_control* If we run out of memory, we have the choice between either* killing a random task (bad), letting the system crash (worse)
