Revision 54aea4542980a3ed580426a81c5af799df4d610d authored by Petr Mladek on 01 October 2015, 22:37:11 UTC, committed by Linus Torvalds on 02 October 2015, 01:42:35 UTC
Commit 3033f14ab78c ("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. Let's use _do_fork() in the kprobe examples to make them work again on all architectures.
