From: Masami Hiramatsu Date: Tue, 16 Mar 2010 22:05:44 +0000 (-0400) Subject: perf probe: Rename session to param X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=12a1fadb41b5a6733c36b488b881fb19a28c92d3;p=linux-beck.git perf probe: Rename session to param Since this name 'session' conflicts with 'perf_session', and this structure just holds parameters anymore.
