[Xen-devel] [PATCH] PoD: Handle operations properly when domain is dying

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

Handle PoD operations properly when a domain is dying.

No populate-on-demand activities should happen when a domain is dying.
 Especially, it is a bug for memory to be added to the PoD cache when
d->is_dying is non-zero, since if this happens after the cache has
been emptied, these pages will never be freed. This may cause "zombie
domains" to linger.
