Currently, cma users can't increase or decrease the cma reference count. This is necassary when setting cma attributes (like the default GID type) in order to avoid use-after-free errors. Adding cma_ref_dev and cma_deref_dev APIs. Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
