[Xen-devel] [PATCH] shadow: fix race between resync and page promotion.
Hi,
This patch fixes a (hopefully) rare-occurring problem causing memory
corruption in 64 bit guests (and assertion failures in debug build xen).
On a pagefault, set_l{3,4}e''s resync_all was able to give write access
to a page in the guest still not shadowed.
This fix should be applied to Xen-3.3 as well.
