From 25239fd338aa2995f04ce3dc3ef3c01488bd05b3 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Wed, 19 Aug 2020 12:46:52 +0200 Subject: [PATCH] kprobes: switch to kernel_clone() The old _do_fork() helper is removed in favor of the new kernel_clone() helper. The latter adheres to naming conventions for kernel internal syscall helpers.
