True, it's often used in return statements, but after much bikeshedding it's probably better to have an explicit name. (I tried just putting the IS_ERR check inside PTR_ERR itself and gcc usually generated no more code. But that clashes current expectations of how PTR_ERR behaves, so having a separate function is better). Suggested-by: Julia Lawall <julia.lawall@lip6.fr> Suggested-by: "Michael S.
