Descriptions

In the Linux kernel, the following vulnerability has been resolved:

i40e: Do not use WQ_MEM_RECLAIM flag for workqueue

Issue reported by customer during SRIOV testing, call trace:
When both i40e and the i40iw driver are loaded, a warning
in check_flush_dependency is being triggered. This seems
to be because of the i40e driver workqueue is allocated with
the WQ_MEM_RECLAIM flag, and the i40iw one is not.

Similar error was encountered on ice too and it was fixed by
removing the flag. Do the same for i40e too.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i40e: no utilice el indicador WQ_MEM_RECLAIM para la cola de trabajo Problema informado por el cliente durante las pruebas SRIOV, seguimiento de llamadas: cuando se cargan tanto el i40e como el controlador i40iw, se activa una advertencia en check_flush_dependency. Esto parece deberse a que la cola de trabajo del controlador i40e está asignada con el indicador WQ_MEM_RECLAIM, y la del i40iw no. También se encontró un error similar en el ice y se solucionó quitando la bandera. Haz lo mismo con el i40e también.
