| |
Hi all,
After merging the akpm-current tree, today's linux-next build (x86_64 allmodconfig) failed like this:
drivers/gpu/drm/nouveau/nouveau_dmem.c:299:11: error: initialization of 'vm_fault_t (*)(struct hmm_devmem *, struct vm_area_struct *, long unsigned int, const struct page *, unsigned int, pmd_t *)' {aka 'unsigned int (*)(struct hmm_devmem *, struct vm_area_struct *, long unsigned int, const struct page *, unsigned int, struct <anonymous> *)'} from incompatible pointer type 'int (*)(struct hmm_devmem *, struct vm_area_struct *, long unsigned int, const struct page *, unsigned int, pmd_t *)' {aka 'int (*)(struct hmm_devmem *, struct vm_area_struct *, long unsigned int, const struct page *, unsigned int, struct <anonymous> *)'} [-Werror=incompatible-pointer-types] .fault = nouveau_dmem_fault, ^~~~~~~~~~~~~~~~~~ drivers/gpu/drm/nouveau/nouveau_dmem.c:299:11: note: (near initialization for 'nouveau_dmem_devmem_ops.fault')
Caused by commit
5be73b690875 ("drm/nouveau/dmem: device memory helpers for SVM")
from the drm tree interacting with commit
ed814eb7f91d ("mm/hmm: convert to use vm_fault_t")
from the akpm-current tree.
I added this merge fix patch:
