From b7b0c51f1fd54c666e9520e1166e24216cc72211 Mon Sep 17 00:00:00 2001 From: Mathias Fröhlich <mathias.froehlich@web.de> Date: Sun, 14 Aug 2016 14:03:58 +0200 Subject: mesa: Move _mesa_all_buffers_are_unmapped to arrayobj.c. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the function to check if all vao buffers are unmapped into the vao implementation file. Rename the function to _mesa_all_buffers_are_unmapped.
