From 005a1aeac46666e2805f316596893ebd2a3c12e7 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 13 Mar 2018 20:07:05 +0100 Subject: net: socket: add __sys_shutdown() helper; remove in-kernel call to syscall Using the net-internal helper __sys_shutdown() allows us to avoid the internal calls to the sys_shutdown() 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.
