Port of commit ae45d7e6d8e6844cd4586c9ee97c21b257fa788f in xf86-video-ati.

Currently this change is a no-op, because can_exchange returns true only when page flipping is enabled, but commit 169512fbe91f0671a90dfee5e280357f0a4ef701 - which changed can_exchange behavior - is due to be reverted) --- src/nouveau_dri2.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/nouveau_dri2.c b/src/nouveau_dr...

Francisco Jerez argument against including it was that the
