| |
Hi all,
After merging the drm tree, today's linux-next build (x86_64 allmodconfig) failed like this:
samples/vfio-mdev/mbochs.c:827:3: error: 'struct dma_buf_ops' has no member named 'map_atomic' .map_atomic = mbochs_kmap_atomic_dmabuf, ^~~~~~~~~~ samples/vfio-mdev/mbochs.c:827:18: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init] .map_atomic = mbochs_kmap_atomic_dmabuf, ^~~~~~~~~~~~~~~~~~~~~~~~~ samples/vfio-mdev/mbochs.c:827:18: note: (near initialization for 'mbochs_dmabuf_ops') samples/vfio-mdev/mbochs.c:827:18: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] samples/vfio-mdev/mbochs.c:827:18: note: (near initialization for 'mbochs_dmabuf_ops.unmap')
Caused by commit
f664a5269542 ("dma-buf: remove kmap_atomic interface")
interacting with commit
a5e6e6505f38 ("sample: vfio bochs vbe display (host device for bochs-drm)")
from Linus' tree (v4.18-rc1).
I added the following just to disable the sample code until it can be repaired.

it was broken by the removal of the dmap-buf kmap_atomic interface.
