[PATCH 0/2] Document the DMA-buf mapping lifetime negotiation

DMA-buf lets an exporter pin, move or revoke the backing storage under
an importer, and which of the three applies is decided by the optional
callbacks each side implements and by whether dma_buf_pin() succeeds.
Nothing in Documentation/ describes that, and the single reference to
the mechanism still names move_notify(), removed in v7.1.

Thanks
