I think oz_trace is a poor name.
It implies you're using the trace subsystem
trace_flags as a global name is also poor
g_oz_wpan_dev is too as it limits the module to
a single dev instance.

I suggest:

#define oz_dbg(level, fmt, ...)					\
do {								\
	if (level & oz_dbg_mask)				\
		dev_dbg(g_oz_wpan_dev, fmt, ##__VA_ARGS__);	\
} while (0)

or better avoiding the single dev:

#define oz_dbg(level, dev, fmt, ...)				\
do {								\
	if (level & oz_dbg_mask)				\
		dev_dbg(dev, fmt, ##__VA_ARGS__);		\
} while (0)

No, just use the built-in dynamic debug code in the kernel, no need to
provide any new macros or functions or most importantly, no new Kconfig
options.

I think the Kconfig option is pretty poor too but a
long needed extension to dev_dbg is to enable classes
of messages by level or mask.

There are many existing macros like

#define module_dbg(level, fmt, ...)
do {
	if (level >= some_module_var)
		debug_something(...);
} while (0)

and

#define module_dbg(mask, fmt, ...)
do {
	if (mask & some_module_var)
		debug_something(...)
} while (0)

It'd be nice to consolidate those in dev_dbg

I'll get 'round to it one day if Jason doesn't.

I'd almost recommend that all of them just be removed, because most of
them were only used for debugging the code the first time it was
developed, right?  Only for very limited usages would this type of thing
be needed.

New macro (oz_trace) is being used as pointer to "struct device *" is 
not available in all functions for dev_dbg() function.
Please let me know if there is better way to handle this, I will be 
happy to rework on this.

As well new Kconfig option was added to pass CFLAGS to compiler, so that 
dev_dbg will get compiled on system where DYNAMIC_DEBUG is not defined.
I was assuming that it is a standard practice, as I can find similar 
Kconfig option for other drivers. Or am I wrong in my understanding ?

Main idea here is to replace printk with dev_dbg(), which gives us 
option to enable individual log during runtime if DYNAMIC_DEBUG is 
enabled & provide mechanism to compile this when DYNAMIC_DEBUG is not 
enabled.

Again many of these logs will be removed in future, as currently there 
are too many logs which are not required, hence idea is to only change 
macro & then remove remaining logs in future.

It depends on the situation.  In many cases there _is_ a struct device
associated with the log message, even if a pointer to that device isn't
available in the function.  The proper solution in those cases is to
make it available, by passing the function an extra "struct device *"
argument.

In a few cases there really is no device associated with the message.  
For example, if the module prints out a message when it is first 
loaded, there probably is no device around at that time.  However, in 
most cases there _is_ an associated device.

Maybe, though that's hard to know with certainty.
How often module options are used isn't easy to find out.

These forms are sometimes used to reduce object size.

Then use pr_debug() for the places you don't have a struct device *,
everywhere else should use dev_dbg().

No, just rely on the overall config option, do you really think the
kernel should have an individual Kconfig debug option for every
individual driver?  We have been removing these for years, don't move
backwards in this area please.

Those options for those drivers should be removed, they were added
before we had the dynamic debug option.  New drivers shouldn't have this
at all.

No, remove the unneeded calls now, why wait?

Hey Jason.  Your redhat.com address is out of date.

If you're still interested in dynamic_debug, you should
update your MAINTAINERS entry.

[PATCH] staging: ozwpan: Use normal Makefile, convert oz_trace to oz_dbg

[Joe Perches]

Use a normal Makefile.
Convert oz_trace and oz_trace2 to a more normal oz_dbg.
Consolidate oztrace and ozconfig files to ozdbg.h
Update #include files.
Reflow modified lines, fit to 80 cols, align arguments.

Add a couple more oz_<foo>_dbg macros to show how more
verbose device specific debugging could be added when a
struct device * or struct netdevice * is available.

Isn't this patch doing too many changes in single patch? Can we split 
this patch into smaller patch series ?
In addition to above, it also :-
1. Removes few unwanted logs.
2. Changes macro definition for oz_remember_urb() & oz_forget_urb() to 
static inline function when WANT_URB_PARANOIA is not defined.

Above macros look good, however Greg have objection to define new macros 
& he had suggested to use dev_dbg() & pr_debug().
I will leave it to him, if he is all right to accept new macros for 
debug logs.

Greg,
Your comments please.

Yeah, sure, please do.
It was intended more to inform than be applied.
staging is closed for at least a few weeks.
Resubmit something like it in as many pieces
as you choose later.

These macros already use pr_debug and should
use dev_dbg and netdev_dbg where appropriate
and possible.  These uses also don't depend
on a single saved global "struct device *".

The grouping/verbose flags are just as you
use them now, but a lot simpler and allow
an easy conversion to a runtime module_param.

Hi,

I've been a bit reluctant to add these 'flag' and 'level' to dynamic
debug b/c the debug statements can already be controlled individually,
and thus one could implement something pretty similar in userspace.
Also, it keeps things simpler.

That said, this has come up several times and might be a nice extension
for both the dynamic debug and non-dynamic debug case.

I think the interface could look something like:

pr_debug_level(&control_var, level, fmt, ...);
pr_debug_mask(&control_var, mask, fmt, ...);

and then you could do something like:

echo "grouping control_var level N +p" > /debugfs/dynamic_debug/control

or

echo "grouping control_var mask 0xN +p" > /debugfs/dynamic_debug/control

So we can think of the 'control_var' as 'grouping' debug statements
together. So it would provide a nice way of associating statements
together other than the existing: module, func, file, format, and line
selectors.

Thanks,

-Jason

As well as making them compatible with the current
module debug control vars by using their address when
appropriate.

Greg,

Can I expect to merge following patch series with your tree ?

Or do you want me to rework on it as per your suggestions here :-

At the least, please rework them as Joe asked you to, why haven't you
done that?

And yes, ideally I'd like to see my suggestion implemented as well.

And yes, ideally I'd like to see my suggestion implemented as well.

All right, I will resend patch series with detailed commit log.
However previous patch series (From Joe) adds new macro on top of pr_dbg() & netdev_dbg(). Is that all right ?

I believe rest of your suggestions are already included in above patch series. 
Please let me know if I have missed anything here.

[PATCH v3 1/5] staging: ozwpan: Remove extra debug logs.

[Rupesh Gujare]

From: Joe Perches <joe@perches.com>

Remove unnecessary debug logs. Most of these logs
print function name at the start of function, which
are not really required.

[PATCH v3 2/5] staging: ozwpan: Replace oz_trace with oz_dbg

[Rupesh Gujare]

From: Joe Perches <joe@perches.com>

Introduce new debug macros: oz_dbg, oz_cdev_dbg, oz_pd_dbg
and then replace old oz_trace & oz_trace2 with new macro.
