When DEBUG is defined, dev_dbg_ratelimited uses dynamic debug data
structures even when CONFIG_DYNAMIC_DEBUG is not defined.
It leads to build break.
For example, when I try to use dev_dbg_ratelimited in USB code and
CONFIG_USB_DEBUG is enabled, but CONFIG_DYNAMIC_DEBUG is not, I get:
CC [M] drivers/usb/host/xhci-ring.o
drivers/usb/host/xhci-ring.c: In function ‘xhci_queue_intr_tx’:

make[1]: *** [drivers/usb/host] Error 2
make: *** [drivers/usb/] Error 2
This patch separates definition for CONFIG_DYNAMIC_DEBUG and DEBUG cases.

When debug is not enabled and dev_dbg() will expand to nothing,
log might be flooded with "callbacks suppressed". If it was not
done on purpose, better to use dev_dbg_ratelimited() instead.

Jason?
Seems mostly sensible to me but I think the first check
needs to be
#if defined(CONFIG_DYNAMIC_DEBUG) && defined(DEBUG)
Also, it's curious why it was ever using __dynamic_pr_debug
instead of __dynamic_dev_dbg
Maybe for completeness there should be a
dev_vdbg_ratelimited too.

Why? All the other call-sites, do it the way Dmitry has done it.

Not sure.

I could also see the rate limiting being pushed further down, such that
dynamic debug could control how and whether or not its enabled.

Hi Dmitry,
This patch looks fine, and applies ok. I'll send it off to Greg with a
couple more bug fixes shortly.

Fine. Originally I thought it useful to not
store the ratelimit state, but this way those
messages can be enabled via the dynamic_debug
control.

I'm just going to fix the first warning myself by moving your comment
above the macro. Please don't add comments inside macros, and please
run your patches through checkpatch.pl.

I run checkpatch always.
The first warning is in my understanding is not related to comments
inside macro,
but just that avoid using "\".
I would not remove comment, because it is for explaining the macro line...
Second warning is natural in this case because macro itself defines
dev_dbg() functionality.
Internally it must use something else than itself...

Any objections to queuing this patch through Greg's usb-next tree? I've
already sent the 2/2 patch, which will cause build breakage without this
patch.
Changes since v2:
- Fixed a checkpatch warning caused by a comment in a macro.

From: Dmitry Kasatkin <d.kasatkin@samsung.com>
When DEBUG is defined, dev_dbg_ratelimited uses dynamic debug data
structures even when CONFIG_DYNAMIC_DEBUG is not defined.
It leads to build break.
For example, when I try to use dev_dbg_ratelimited in USB code and
CONFIG_USB_DEBUG is enabled, but CONFIG_DYNAMIC_DEBUG is not, I get:
CC [M] drivers/usb/host/xhci-ring.o
drivers/usb/host/xhci-ring.c: In function ‘xhci_queue_intr_tx’:
drivers/usb/host/xhci-ring.c:3059:3: error: implicit declaration of function ‘DEFINE_DYNAMIC_DEBUG_METADATA’ [-Werror=implicit-function-declaration]

cc1: some warnings being treated as errors
make[2]: *** [drivers/usb/host/xhci-ring.o] Error 1
make[1]: *** [drivers/usb/host] Error 2
make: *** [drivers/usb/] Error 2
This patch separates definition for CONFIG_DYNAMIC_DEBUG and DEBUG cases.
[Note, Sarah moved the comment above the macro to avoid checkpatch
warnings.]
