226 | oom_kill_allocating_task | ||
227 | |||
228 | This enables or disables killing the OOM-triggering task in | ||
229 | out-of-memory situations. | ||
230 | |||
231 | If this is set to zero, the OOM killer will scan through the entire | ||
232 | tasklist and select a task based on heuristics to kill. This normally | ||
233 | selects a rogue memory-hogging task that frees up a large amount of | ||
234 | memory when killed. | ||
235 | |||
236 | If this is set to non-zero, the OOM killer simply kills the task that | ||
237 | triggered the out-of-memory condition. This avoids the expensive | ||
238 | tasklist scan. | ||
239 | |||
240 | If panic_on_oom is selected, it takes precedence over whatever value | ||
