From: Arnaldo Carvalho de Melo Date: Fri, 5 Mar 2010 21:23:50 +0000 (-0300) Subject: tracing: Update the comm field in the right variable in update_max_tr X-Git-Tag: v2.6.34-rc2~52^2~5^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1acaa1b2d9b5904c9cce06122990a2d71046ce16;p=pandora-kernel.git tracing: Update the comm field in the right variable in update_max_tr The latency output showed: # | task: -3 (uid:0 nice:0 policy:1 rt_prio:99) The comm is missing in the "task:" and it looks like a minus 3 is the output. The correct display should be: # | task: migration/0-3 (uid:0 nice:0 policy:1 rt_prio:99) The problem is that the comm is being stored in the wrong data structure. The max_tr.data[cpu] is what stores the comm, not the tr->data[cpu]. Before this patch the max_tr.data[cpu]->comm was zeroed and the /debug/trace ended up showing just the '-' sign followed by the pid. Also remove a needless initialization of max_data.
