Previous versions. v3: https://lore.kernel.org/dri-devel/20201120095445.1195585-1-daniel.vetter@ffwll.ch/ v2: https://lore.kernel.org/dri-devel/20200610194101.1668038-1-daniel.vetter@ffwll.ch/ Changes since v3: - more acks/r-b - typos in the kerneldoc fixed Changes since v2: - Now hopefully the bug that bombed xfs fixed. - With unit-tests (that's the part I really wanted and never got to) - might_alloc() helper thrown in for good. I think if we have an ack/review from fs-devel this should be good to land. Last version that landed in -mm (v2) broke xfs pretty badly. Unfortuantely I don't have a working email from Qian anymore, who reported the xfs issue. Maybe Dave Chinner instead?
