driver ABI, because a new method will need to be added to struct
ibv_context_ops.
- * Eliminate the dependency on libsysfs by implementing the required
- sysfs handling directly. This will break the API, because the dev
- and ibdev members of struct ibv_device will be removed. It will
- also break the device driver ABI, because the signature of the
- driver initialization function will change. The driver
- initialization function will be changed as part of this work; this
- has the added benefit of allowing us to choose a better name than
- "openib_driver_init."
