Subject : [OOPS] 2.6.39.x latencytop Submitter : Andrew Watts <firstname.lastname@example.org> Date : 2011-06-14 17:07 Message-ID : email@example.com References : http://marc.info/?l=linux-kernel&m=130807128506490&w=2 This entry is being used for tracking a regression from 2.6.38. Please don't close it until the problem is fixed in the mainline.
Comment 1 Florian Mickler 2011-06-26 14:09:08 UTC
This is't an OOPS, it is a WARNING... As far as I see, the corresponding code looks like: WARN_ONCE(1, "tracing_enabled is deprecated. Use tracing_on"); Does this indeed turn up in your dmesg? latencytop should probably do a s/\btracing_enabled\b/tracing_on/ in it's fsync.c file.
Comment 2 akwatts 2011-06-27 15:49:21 UTC
It is indeed a warning not an oops. I get it in my syslog logfile which means it is kernel.warn or higher. Please note the separately-filed bug report at (bug #37652) as well as Steven Rostedt's comments.
Comment 3 Florian Mickler 2011-06-27 21:20:55 UTC
Ah yes. Thanks for the reference. I just send Arjan a patch for latencytop, though I don't really understand the need for this renaming.
