From 4b7ca5014cbef51cdb99fd644eae4f3773747a05 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 22 Jul 2020 11:26:13 +0200 Subject: init: add an init_chroot helper Add a simple helper to chroot with a kernel space file name and switch the early init code over to it. Remove the now unused ksys_chroot.
