[PATCH rdma-next 1/6] RDMA/umem: Remove redundant DMABUF ops check

From: Leon Romanovsky
Date: Sun Jan 04 2026 - 08:52:08 EST


From: Leon Romanovsky <leonro@xxxxxxxxxx>

ib_umem_dmabuf_get_with_dma_device() is an in-kernel function and does
not require a defensive check for the .move_notify callback. All current
callers guarantee that this callback is always present.
