Subject: [PATCH 0/2] KVM: async_pf: use_mm/mm_users fixes

Hello.

Completely untested and I know nothing about kvm ;) Please review.

But use_mm() really looks misleading, and the usage of mm_users looks
"obviously wrong". I already sent this change while we were discussing
vmacache, but it was ignored. Since then kvm_async_page_present_sync()
was added into async_pf_execute() into async_pf_execute(), but it seems
to me that use_mm() is still unnecessary.

Oleg.
