commit 07f515979e06d4fdc6d09daa19335e91083a96f8 (HEAD, upstream/master) Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Oct 20 11:18:01 2017 +0100 igt/gem_fd_exhaustion: Remove stale assert __gem_create() doesn't touch the outparam *handle on failure, so we can no longer assert that it zero. This is reasonable to remove as it is just testing the library itself and not the kernel, so no loss in coverage. We already had to remove the false assertion that gem_create() must fail following fd exhaustion (as we can not prevent the kernel from freeing VFS fdspace in between calls). This bug is fixed, closing. |
