Subject: [PATCH tip/master ] ftracetest: Update kprobe-tracer testcases
because of renaming do_fork
Since the commit 3033f14ab78c ("clone: support passing tls argument via
C rather than pt_regs magic") renames do_fork to _do_fork, the testcases
for kprobe-tracer doesn't work correctly on the latest kernel.
This fixes it by changing do_fork to _do_fork.
