commit 4b81e9ca7df84d3c8775ebf0332f7444cafe8e77 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Sep 19 16:40:00 2014 +0100 igt/gem_reloc_vs_gpu: Fix reloc.presumed_offset value Since the last patched value does not match the presumed relocation value we submit to the kernel, it occasionally makes mistakes. Also note that the libdrm interface makes the same presumptive mistake, and would easily be broken by a threaded environment.
