Subject: [PATCH v2 08/11] kprobes: switch to kernel_clone()
Date: Wed, 19 Aug 2020 12:46:52 +0200 [thread overview]
Message-ID: <20200819104655.436656-9-christian.brauner@ubuntu.com> (raw)
In-Reply-To: <20200819104655.436656-1-christian.brauner@ubuntu.com>
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.
