That\u0027s fine; we\nhave a fallback to instead use the cpuset mask. However, we have a WARN\nset up that will trigger if the cpuset mask has no overlap at all with\nthe requested task affinity. This shouldn\u0027t be a warning condition; its\ntrivial to create this condition.\n\nReproduced the warning by the following setup:\n\n- $PID inside a cpuset cgroup\n- another thread repeatedly switching the cpuset cpus from 1-2 to just 1\n- another thread repeatedly setting the $PID affinity (via taskset) to 2"

Espec\u00edficamente, podemos tener una ejecuci\u00f3n donde una actualizaci\u00f3n de cpuset da como resultado que la afinidad de la tarea ya no sea un subconjunto del cpuset. Eso est\u00e1 bien; tenemos una alternativa para usar la m\u00e1scara de cpuset. Sin embargo, tenemos una ADVERTENCIA configurada que se activar\u00e1 si la m\u00e1scara de cpuset no se superpone en absoluto con la afinidad de la tarea solicitada. Esto no deber\u00eda ser una condici\u00f3n de advertencia; es trivial crear esta condici\u00f3n. Se reprodujo la advertencia con la siguiente configuraci\u00f3n: - $PID dentro de un cgroup de cpuset - otro hilo que cambia repetidamente las CPU de cpuset de 1-2 a solo 1 - otro hilo que establece repetidamente la afinidad $PID (a trav\u00e9s del conjunto de tareas) en 2"
