As a preparation to extension of rdma_restrack_root to provide software IDs, which will be per-type too. We convert the rdma_restrack_root from struct with arrays to array of structs. Such conversion allows us to drop rwsem lock in favour of internal XArray lock. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
