| |
Hi all,
After merging the mm tree, today's linux-next build (x86_64 allmodconfig) failed like this:
drivers/accel/ivpu/ivpu_gem.c: In function 'ivpu_bo_mmap': drivers/accel/ivpu/ivpu_gem.c:449:23: error: assignment of read-only member 'vm_flags' 449 | vma->vm_flags |= VM_PFNMAP | VM_DONTEXPAND; | ^~
Caused by commit
b95a895848b9 ("mm: introduce vma->vm_flags wrapper functions")
interacting with commit
647371a6609d ("accel/ivpu: Add GEM buffer object management")
from the drm tree.
I have applied the following merge fix patch for today.
