Subject[PATCH 0/2] clone/kprobe: Do not use do_fork() when not defined
Date
The commit 3033f14ab78c32687 ("clone: support passing tls argument via C
rather than pt_regs magic") introduced _do_fork() that allowed to pass
@tls parameter.

The old do_fork() is defined only for architectures that are not ready
to use this way and do not define HAVE_COPY_THREAD_TLS.

1st patch fixes do_fork() declaration.

2nd patch fixes kprobe samples to work again.

BTW: I think about renaming _do_fork() to do_fork_tls(). Then it will
use the same naming scheme as copy_thread()/copy_thread_tls().

Petr Mladek (2):
clone: Declare do_fork() only when available
kprobe: Use _do_fork() in samples to make them work again
