Sorry for that. I'm sure it doesnt crash if set_gpfn_from_mfn() is called from free_domheap_pages(). Looking at free_heap_pages(), now the page owner is cleared at the beginning of the loop. But later in the loop it is checked wether a TLB flush is required. So the set_gpfn_from_mfn() should be at least moved past this check. Even if that doesnt fix the crash you are seening. I will see if I can come up with a better version. Olaf _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
