From 808e122630d45a7f036d25582474d70548a87e2c Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 14 Feb 2012 14:18:57 -0200 Subject: perf tools: Invert the sample_id_all logic Instead of requiring that users of perf_record_opts set .sample_id_all_avail to true, just invert the logic, using .sample_id_all_missing, that doesn't need to be explicitely initialized since gcc will zero members ommitted in a struct initialization. Just like the newly introduced .exclude_{guest,host} feature test.
