tracing: Move a printk out of ftrace_raw_reg_event_foo()

2009-12-13T17:37:25Z

Move the printk from each ftrace_raw_reg_event_foo() to its caller ftrace_event_enable_disable(). This avoids each regfunc trace event callbacks to handle a same error report that can be carried from the caller. See how much space this saves: text data bss dec hex filename 5345151 1961864 7103260 14410275 dbe223 vmlinux.o.old 5331487 1961864 7103260 14396611 dbacc3 vmlinux.o Signed-off-by: Li Zefan Acked-by: Steven Rostedt Cc: Jason Baron LKML-Reference: <4B1DC4AC.802@cn.fujitsu.com> [start cmdline record before calling regfunc to avoid lost window of pid to comm resolution] Signed-off-by: Frederic Weisbecker

tracing: Pull up calls to trace_define_common_fields()

2009-12-13T17:34:23Z

Call trace_define_common_fields() in event_create_dir() only. This avoids trace events to handle it from their define_fields callbacks and shrinks the kernel code size: text data bss dec hex filename 5346802 1961864 7103260 14411926 dbe896 vmlinux.o.old 5345151 1961864 7103260 14410275 dbe223 vmlinux.o Signed-off-by: Li Zefan Acked-by: Steven Rostedt Cc: Ingo Molnar Cc: Jason Baron Cc: Masami Hiramatsu LKML-Reference: <4B1DC49C.8000107@cn.fujitsu.com> Signed-off-by: Frederic Weisbecker

tracing: Extract duplicate ftrace_raw_init_event_foo()

2009-12-13T17:34:23Z

Use a generic trace_event_raw_init() function for all event's raw_init callbacks (but kprobes) instead of defining the same version for each of these. This shrinks the kernel code: text data bss dec hex filename 5355293 1961928 7103260 14420481 dc0a01 vmlinux.o.old 5346802 1961864 7103260 14411926 dbe896 vmlinux.o raw_init can't be removed, because ftrace events and kprobe events use different raw_init callbacks. Though it's possible to totally remove raw_init, I choose to leave it as it is for now.

Merge branch 'perf/core' into perf/probes

2009-10-23T06:23:20Z

Conflicts: tools/perf/Makefile Merge reason: - fix the conflict - pick up the pr_*() infrastructure to queue up dependent patch Signed-off-by: Ingo Molnar

Merge commit 'v2.6.32-rc5' into perf/probes

Merge branch 'tracing/core' into perf/core

2009-10-15T09:34:00Z

Merge reason: to add event filter support we need the following commits from the tracing tree: 3f6fe06: tracing/filters: Unify the regex parsing helpers 1889d20: tracing/filters: Provide basic regex support 737f453: tracing/filters: Cleanup useless headers Signed-off-by: Ingo Molnar

tracing/events: Add 'signed' field to format files

2009-10-06T13:04:45Z

The sign info used for filters in the kernel is also useful to applications that process the trace stream. Add it to the format files and make it available to userspace.

tracing/ftrace: Fix to check create_event_dir() when adding new events

2009-10-03T01:04:58Z

Check result of event_create_dir() and add ftrace_event_call to ftrace_events list only if it is succeeded. Thanks to Li for pointing it out.

tracing/event: Cleanup the useless dentry variable

2009-09-24T13:27:41Z

Cleanup the useless dentry variable while creating a kernel event set of files. trace_create_file() warns if it fails to create the file anyway, and we don't store the dentry anywhere. v2: Fix a small conflict in kernel/trace/trace_events.c Signed-off-by: Frederic Weisbecker Cc: Steven Rostedt Cc: Li Zefan
