Subject: perf script: Use the default lost event handler
X-Git-Tag: v2.6.38-rc1~490^2~3
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=6d8afb56300c53a250c6de0f973ef502e54aabf3;p=~shefty%2Frdma-dev.git

perf script: Use the default lost event handler

That already does what was being done here. The warning is now unconditionally
given by __perf_session__process_pipe_events, just like for non pipe processing.
