tracing: Remove orphaned function using_ftrace_ops_list_func(). (7b144b6c) · Commits · 戴 / test

Remove using_ftrace_ops_list_func() since it is no longer used. Using ftrace_ops_list_func() has been introduced by commit ("tracing/stack_trace: Skip 4 instead of 3 when using ftrace_ops_list_func") as a helper function, but its caller has been removed by commit ("tracing: Clean up stack tracing and fix fentry updates"). So it is not called anymore. Link: http://lkml.kernel.org/r/153260904427.12474.9952096317439329851.stgit@devbox Signed-off-by:
