[Xen-devel] Is this a data corruption bug for p2m_ram_shared page in hvm_hap_nested_page_fault()



Hi,

In hvm_hap_nested_page_fault(), it seems that all valid write faults are now 
handled
by p2m_mem_access_check(), right? Then when will mem_sharing_unshare_page()
be called? And if p2m->access_required == false, the access restrictions is 
cleared
, then the data in this shared page could be corrupted by this page write 
access?


Thanks,

Nai
