Hi John,
After merging the wireless tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
WARNING: drivers/net/wireless/iwlwifi/iwlagn: 'iwl_legacy_tx_cmd_protection' exported twice. Previous export was in drivers/net/wireless/iwlwifi/iwl3945.ko
WARNING: drivers/net/wireless/iwlwifi/iwlagn: 'iwl_isr_legacy' exported twice. Previous export was in drivers/net/wireless/iwlwifi/iwl3945.ko

I have done that as well for today in linux-next.

The only problem I could see with that is is there are some inline
functions in the headers files between where the first and second #define
pr_fmt s get done.

John,
I thought about that particular strategy (doing the #undef) instead of
the non-traditional include mess. But not being familiar enough with
the pr_fmt stuff, I didn't want to do it.
My goal was to get the '#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt'
line in the deb_defs.h header so it was only in one place. But to
build, that define must be before kernel.h gets included anywhere.
Hence the current mess.
I'm OK with the #undef strategy and moving the deb_defs.h include to a
better position if that's the correct way to do this. Please let me
know if I have any action items on this.

Right. So in wireless-testing I did the includes in the other order
(i.e. "deb_defs.h" first), but that is a bit ugly. Any suggestions
on alternatives?
"#undef pr_fmt" just before the "#define pr_fmt(fmt)..." line in
db_defs.h seems to eliminate the warning even with the more normal
ordering of the #include lines. I'm not familiar with the usage of
pr_fmt -- will doing the above preserve the desired effect?

Hi John,
After merging the wireless tree, today's linux-next build (x86_64 allmodconfig)
produced these warnings:

Presumably this is caused by the merge fixup I did that explicitly
includes linux/slab.h before deb_defs.h. So you may want to try a
different merge fix.
