Description
BeOS made sure the memory buffer passed to a device read/write was safe to be written to. Haiku currently requires the drivers to use user_memcpy() to access those buffers, which is not compatible to how the old driver interface works.
Also, the new file system interface doesn't solve this issue yet, either...
