There are two complications in this code. First, __dev_alloc_name() clobbers its output arg even if allocation fails, forcing callers to do extra copies. Second as our experience in commit 55a5ec9b7710 ("Revert "net: core: dev_get_valid_name is now the same as dev_alloc_name_ns"") and commit 029b6d140550 ("Revert "net: core: maybe return -EEXIST in __dev_alloc_name"") taught us, user space is very sensitive to the exact error codes. Align the callers of __dev_alloc_name(), and remove some of its complexity. v1: https://lore.kernel.org/all/20231020011856.3244410-1-kuba@kernel.org/ ==================== Link: https://lore.kernel.org/r/20231023152346.3639749-1-kuba@kernel.org Signed-off-by: Jakub Kicinski --- fcc017e3bc7ffff81d6d79678b3d5f6ce99b66ca
