Well, .streamoff is handled by v4l2_m2m_streamoff, which
guarantees that no job is running by calling v4l2_m2m

Subject: [PATCH 25/34] videobuf2-v4l2: add vb2_request_queue/validate helpers
The generic vb2_request_validate helper function checks if
there are buffers in the reques
For mem2mem devices we have to make sure that v4l2_m2m_try_schedule()
is called whenever a request is queued.
We do that by creating a vb2_m2m_request_queue() helper that should
be used instead of the 'normal' vb2_request_queue() helper. The m2m
helper function will call v4l2_m2m_try_schedule() as
12 matches
