Descriptions

P2M pool freeing may take excessively long The P2M pool backing second level address translation for guests may be of significant size. Therefore its freeing may take more time than is reasonable without intermediate preemption checks. Such checking for the need to preempt was so far missing.

La liberación del pool P2M puede tardar demasiado El pool P2M que respalda la traducción de direcciones de segundo nivel para huéspedes puede tener un tamaño considerable. Por lo tanto, su liberación puede tomar más tiempo de lo que es razonable sin comprobaciones intermedias de preferencia. Esta comprobación de la necesidad de adelantarse no existía hasta ahora
