Subject: dri3: use invalidate.
X-Git-Tag: upstream/10.3~1316
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e40cf256f4cb4105c760060e43ab19a4f1524ed3;p=platform%2Fupstream%2Fmesa.git

dri3: use invalidate.

This doesn't change anything to the intel DRI3 implementation,
but enables the gallium implementation to use dri2.stamp instead
of relying on the stamp shared with the st backend.
