From db63f1e315384590b979f8f74abd1b5363b69894 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 22 Jul 2020 11:25:21 +0200 Subject: init: add an init_chdir helper Add a simple helper to chdir with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_chdir.
