> Changes since v1:
> Added changes in these files:
> All these functions either return a negative error indicator,
> or store length of sockaddr into "int *socklen" parameter
> and return zero on success.
> "int *socklen" parameter is awkward. For example, if caller does not
> care, it still needs to provide on-stack storage for the value
> it does not need.
> None of the many FOO_getname() functions of various protocols
> ever used old value of *socklen. They always just overwrite it.
> This change drops this parameter, and makes all these functions, on success,
> return length of sockaddr. It's always >= 0 and can be differentiated
> from an error.
> Tests in callers are changed from "if (err)" to "if (err < 0)", where needed.
> rpc_sockname() lost "int buflen" parameter, since its only use was
> to be passed to kernel_getsockname() as &buflen and subsequently
> not used in any way.
> Userspace API is not changed.

Applied to net-next, thanks Denys.
