Hello, In vb2_cma_put if buf->refcount is 0, cma_free is called. But vb2_cma_put is usually called from munmap. In my opinion cma_free should be called from VIDIOC_REQBUFS(0) not munmap.
cma_free has to be called from both, since we do not always call VIDIOC_REQBUFS(0) after finishing. If an application just closes the file descriptor (or even dies), we need a way to clean up the memory. -- Best regards, Pawel Osciak -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
