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. > > text data bss dec hex filename > 30108430 2633624 873672 33615726 200ef6e vmlinux.before.o > 30108109 2633612 873672 33615393 200ee21 vmlinux.o > > Signed-off-by: Denys Vlasenko <dvlasenk@xxxxxxxxxx> Applied to net-next, thanks Denys. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
