From f13903587c189fa73da47ddd416eb31704c48486 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sun, 11 Mar 2018 11:34:29 +0100 Subject: [PATCH] fs: add do_futimesat() helper; remove internal call to sys_futimesat() Using this helper removes the in-kernel call to the sys_futimesat() 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.
