Merge tag 'kernel-clone-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull kernel_clone() updates from Christian Brauner: "During the v5.9 merge window we reworked the process creation codepaths across multiple architectures. After this work we were only left with the _do_fork() helper based on the struct kernel_clone_args calling convention. As was pointed out _do_fork() isn't valid kernelese especially for a helper that isn't just static. This series removes the _do_fork() helper and introduces the new kernel_clone() helper. The process creation cleanup didn't change the name to something more reasonable mainly because _do_fork() was used in quite a few places. So sending this as a separate series seemed the better strategy. I originally intended to send this early in the v5.9 development cycle after the merge window had closed but given that this was touching quite a few places I decided to defer this until the v5.10 merge window" * tag 'kernel-clone-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: sched: remove _do_fork() tracing: switch to kernel_clone() kgdbts: switch to kernel_clone() kprobes: switch to kernel_clone() x86: switch to kernel_clone() sparc: switch to kernel_clone() nios2: switch to kernel_clone() m68k: switch to kernel_clone() ia64: switch to kernel_clone() h8300: switch to kernel_clone() fork: introduce kernel_clone()
