Subject: tracing: Use trace_iterator_reset() in tracing_read_pipe()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2768c1e7f9d7b82f9e129efe3677c783bc77b8f9;p=linux.git

tracing: Use trace_iterator_reset() in tracing_read_pipe()

Currently tracing_read_pipe() open codes trace_iterator_reset(). Just have
it use trace_iterator_reset() instead.
