tracing: Documentation / sample code fixes for tracepoints

2009-03-24T21:32:12Z

Fix the tracepoint documentation to refer to "tracepoint-sample" instead of "tracepoint-example" to match what actually exists; fix the directory, and clarify how to compile. Change every instance of "example" in the sample tracepoint code to "sample" for consistency.

tracing: replace TP `with TP_`

2009-03-10T04:35:04Z

Impact: clean up The macros TPPROTO, TPARGS, TPFMT, TPRAWFMT, and TPCMD all look a bit ugly. This patch adds an underscore to their names. Signed-off-by: Steven Rostedt

samples: mark {static|init|exit} for {init|exit} functions

2009-01-06T23:59:12Z

None of these (init|exit) functions is called from other functions which is outside the kernel module mechanism or kernel itself, so mark them as {static|__init|__exit}.

tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()

2008-11-16T08:01:36Z

Impact: API *CHANGE*. Must update all tracepoint users. Add DEFINE_TRACE() to tracepoints to let them declare the tracepoint structure in a single spot for all the kernel. It helps reducing memory consumption, especially when declaring a lot of tracepoints, e.g. for kmalloc tracing. *API CHANGE WARNING*: now, DECLARE_TRACE() must be used in headers for tracepoint declarations rather than DEFINE_TRACE(). This is the sane way to do it. The name previously used was misleading. Updates scheduler instrumentation to follow this API change. Signed-off-by: Mathieu Desnoyers Signed-off-by: Ingo Molnar

tracepoints: samples, fix teardown

2008-11-16T08:01:30Z

Impact: fix a bug in sample tracepoints Need a tracepoint_synchronize_unregister() before the end of exit() to make sure every probe callers have exited the non preemptible section and thus are not executing the probe code anymore. Signed-off-by: Mathieu Desnoyers Signed-off-by: Ingo Molnar

markers: probe example, fix teardown

kobject: should use kobject_put() in kset-example

2008-07-22T04:54:56Z

We should call kobject_put() instead of kfree() if kobject_init_and_add() returns an error, shouldn't we? Don't set up a bad example ;) Signed-off-by: Li Zefan Signed-off-by: Greg Kroah-Hartman

Firmware: fix typo in example code

2008-07-22T04:54:41Z

It's not like this stuff even builds right now, but this will make Randy's scripts happy :) Cc: Randy Dunlap Signed-off-by: Greg Kroah-Hartman

samples: use non-racy method for /proc/marker-example creation

2008-04-29T15:06:21Z

Use proc_create() to make sure that ->proc_fops be setup before gluing PDE to main tree. Signed-off-by: Denis V. Lunev Cc: Mathieu Desnoyers Cc: Alexey Dobriyan Cc: "Eric W. Biederman" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
