Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

/tmp/next/build/drivers/infiniband/core/ib_core_uverbs.c: In function 'rdma_user_mmap_entry_remove':
/tmp/next/build/drivers/infiniband/core/ib_core_uverbs.c:249:17: error: implicit declaration of function 'dma_buf_move_notify' [-Wimplicit-function-declaration]
249 | dma_buf_move_notify(uverbs_dmabuf->dmabuf);
| ^~~~~~~~~~~~~~~~~~~
make[6]: *** [/tmp/next/build/scripts/Makefile.build:289: drivers/infiniband/core/ib_core_uverbs.o] Error 1
make[6]: *** Waiting for unfinished jobs....
/tmp/next/build/drivers/infiniband/core/uverbs_std_types_dmabuf.c: In function 'uverbs_dmabuf_fd_destroy_uobj':
/tmp/next/build/drivers/infiniband/core/uverbs_std_types_dmabuf.c:170:17: error: implicit declaration of function 'dma_buf_move_notify' [-Wimplicit-function-declaration]
170 | dma_buf_move_notify(uverbs_dmabuf->dmabuf);
| ^~~~~~~~~~~~~~~~~~~
make[6]: *** [/tmp/next/build/scripts/Makefile.build:289: drivers/infiniband/core/uverbs_std_types_dmabuf.o] Error 1

Caused by commit

95308225e5bae (dma-buf: Rename dma_buf_move_notify() to dma_buf_invalidate_mappings())

interacting with

0ac6f4056c4a2 (RDMA/uverbs: Add DMABUF object type and operations)

from Linus' tree. I have fixed this up as below and can carry as
needed.
