From 4541e80560ca56d63348f40f2e34b044a5eb3dd7 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 13 Mar 2018 19:24:23 +0100 Subject: net: socket: add __sys_accept4() helper; remove in-kernel call to syscall Using the net-internal helper __sys_accept4() allows us to avoid the internal calls to the sys_accept4() 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.
