From b21c8f838a0e5b84c0d78fd9ed6b9f2cf97afbe9 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 13 Mar 2018 19:47:00 +0100 Subject: net: socket: add __sys_getpeername() helper; remove in-kernel call to syscall Using the net-internal helper __sys_getpeername() allows us to avoid the internal calls to the sys_getpeername() syscall. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
