[PATCH] xenpaging:add the dealing of MEM_EVENT_FLAG_EVICT_FAIL request in
..._FLAG_EVICT_FAIL request in
tools/xenpaging
If a page is nominated but not evicted,then dom0 accesses the page,it
will change the page''s p2mt to be p2m_ram_paging_in,and the req.flags is
MEM_EVENT_FLAG_EVICT_FAIL;so it will fail in p2m_mem_paging_evict() because
of the p2mt;and paging->num_paged_out will not increase in this case;After
the paging process is terminated, the p2mt p2m_ram_paging_in still remains
in p2m table.Once domU accesses the nominated page,it will result in BSOD
or vm''stuck.
The patch adds the dealing of this request to resume the page before xenpaging
is ended.
