From 211b634b7f1ebc3436d5e8a34810a8eaa1f269d9 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 13 Mar 2018 19:18:52 +0100 Subject: net: socket: add __sys_sendto() helper; remove in-kernel call to syscall Using the net-internal helper __sys_sendto() allows us to avoid the internal calls to the sys_sendto() 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.
