[Xen-devel] Re: [PATCH] mem_sharing: fix race condition of nominate and unshare

[Jui-Hao Chiang <juihaochiang@xxxxxxxxx>]

Hi, all:

I disable Rich formatting in gmail, does the format looks good now?
To tinnycloud: hvm_hap_nested_page_fault() will be called when a guest
writes a shared page.

Inside unshare(), it does the following
(1) page_make_private() --> page_set_owner(page, d) to update
page_info structure. So there is no need for you to add page_set_owner
explicitly.
(2) set_shared_p2m_entry() to update the page table

properly. Could you debug into it also?

Thanks,
