Descriptions

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

nvmet-fc: avoid deadlock on delete association path

When deleting an association the shutdown path is deadlocking because we
try to flush the nvmet_wq nested. Avoid this by deadlock by deferring
the put work into its own work item.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvmet-fc: evita el punto muerto al eliminar la ruta de asociación Al eliminar una asociación, la ruta de cierre se bloquea porque intentamos vaciar el nvmet_wq anidado. Evite este punto muerto al diferir el trabajo colocado en su propio elemento de trabajo.
