Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters") Signed-off-by: Randy Dunlap Cc: Eli Cohen Cc: Saeed Mahameed Cc: netdev@vger.kernel.org Cc: Leon Romanovsky Cc: linux-rdma@vger.kernel.org Reviewed-by: Leon Romanovsky --- drivers/net/ethernet/mellanox/mlx5/core/main.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) --- lnx-517-rc8.orig/drivers/net/ethernet/mellanox/mlx5/core/main.c +++ lnx-517-rc8/drivers/net/ethernet/mellanox/mlx5/core/main.c @@ -1893,7 +1893,7 @@ static void mlx5_core_verify_params(void } } -static int __init init(void) +static int __init mlx5_init(void) { int err; @@ -1929,7 +1929,7 @@ err_debug: return err; } -static void __exit cleanup(void) +static void __exit mlx5_cleanup(void) { mlx5e_cleanup(); mlx5_sf_driver_unregister(); @@ -1937,5 +1937,5 @@ static void __exit cleanup(void) mlx5_unregister_debugfs(); } -module_init(init); -module_exit(cleanup); +module_init(mlx5_init); +module_exit(mlx5_cleanup);
