From 89c8e98d8cfb0656dbeb648572df5b13e372247d Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Fri, 10 Mar 2023 16:03:29 -0600 Subject: [PATCH] fork: allow kernel code to call copy_process The next patch adds helpers like create_io_thread, but for use by the vhost layer. There are several functions, so they are in their own file instead of cluttering up fork.c. This patch allows that new file to call copy_process. Signed-off-by: Mike Christie Acked-by: Michael S.
