Subject: [PATCH 08/11] kprobes: switch to kernel_clone()
Date: Tue, 18 Aug 2020 19:34:08 +0200	[thread overview]
Message-ID: <20200818173411.404104-9-christian.brauner@ubuntu.com> (raw)
In-Reply-To: <20200818173411.404104-1-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.
