[PATCH 0 of 2] xenpaging:speed up page-in
The following two patches are about how to speed up in xenpaging when page in pages.
On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds,
but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause
unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash.
What鈥檚 more,the dom0 is always in high I/O pressure.

[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
...xen-access by using an independent ring buffer for each feature.
Please review.
v2:
- update mem_event_check_ring arguments, check domain rather than domain_id
- check ring_full first because its value was just evaluated
- check if ring buffer is initialized before calling
mem_access_domctl/mem_paging_domctl

Getting the page fault count for domU
Hi
How do we get the number of page faults done by a guest in a scheduling
epoch?
Assuming only one VCPU per guest, can I get it from vcpu_info[]?
I hope this is not a vey trivial question :)
thanks
Chintu
