From 8243186f0cc7c57cf9d6a110cd7315c44e3e0be8 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Tue, 23 Oct 2018 16:24:09 +0200 Subject: fs: remove ksys_dup() ksys_dup() is used only at one place in the kernel, namely to duplicate fd 0 of /dev/console to stdout and stderr. The same functionality can be achieved by using functions already available within the kernel namespace.
