[PATCH 0/2] Trace skipped memory sections at vdpa memory listener

Posted by Eugenio Pérez 9 months, 2 weeks ago

Some memory regions are not being skipped in vhost_vdpa_listener_region_del,
but they are skipped in vhost_vdpa_listener_region_add, or vice versa.  The
vhost-vdpa code expects all parts to maintain their properties, so we're adding
a trace to help with debugging when any part is skipped.
