The patch titled Subject: drm/i915/selftests: use vma_lookup() in __igt_mmap() has been added to the -mm tree. Its filename is drm-i915-selftests-use-vma_lookup-in-__igt_mmap.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/drm-i915-selftests-use-vma_lookup-in-__igt_mmap.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/drm-i915-selftests-use-vma_lookup-in-__igt_mmap.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Liam Howlett <liam.howlett@xxxxxxxxxx> Subject: drm/i915/selftests: use vma_lookup() in __igt_mmap() vma_lookup() will look up the vma at a specific address. find_vma() will start the search for a specific address and continue upwards. This fixes an issue with the selftest as the returned vma may not be the newly created vma, but simply the vma at a higher address.
