Name:rn true if the task is not adequate as candidate victim task.

Proto:static bool oom_unkillable_task(struct task_struct *p)

Type:bool

Parameter:

TypeParameterName
struct task_struct *p
163  If s_global_init - check if a task structure is init. Since init* is free to have sub-threads we need to check tgid.*@tsk: Task structure to be checked.* Check if a task structure is the first user space task the kernel created. Then Return true

167  Return false
Caller
NameDescribe
oom_badnessm_badness - heuristic function to determine which candidate task to kill*@p: task struct of which task we should calculate*@totalpages: total present RAM allowed for page allocation* The heuristic for determining which task to kill is made to be as simple
oom_evaluate_task
dump_task
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)
