Commit eba9ebaaa26d "firewire: sbp2: use dev_printk API" changed
messages from e.g.
firewire_sbp2: fw3.0: logged in to LUN 0000 (0 retries)
to
sbp2 fw3.0: logged in to LUN 0000 (0 retries)
because the driver calls itself as "sbp2" when registering with driver
core and with SCSI core. This is of course confusing, so switch to the
name "firewire_sbp2" for driver core in order to match what lsmod and
/sys/module/ show. So we are back to
firewire_sbp2 fw3.0: logged in to LUN 0000 (0 retries)
in the kernel log.
This also changes
/sys/bus/firewire/drivers/sbp2
/sys/bus/firewire/devices/fw3.0/driver -> [...]/sbp2
/sys/module/firewire_sbp2/drivers/firewire:sbp2
to
/sys/bus/firewire/drivers/firewire_sbp2
/sys/bus/firewire/devices/fw3.0/driver -> [...]/firewire_sbp2
/sys/module/firewire_sbp2/drivers/firewire:firewire_sbp2
but "cat /sys/class/scsi_host/host27/proc_name" stays "sbp2" just in
case that proc_name is used by any userland.
The transport detection in lsscsi is not affected. (Tested with lsscsi
version 0.25.) Udev's /dev/disk/by-id and by-path symlinks are not
affected either.

On second thought, there is little reason to have driver name differ
from module name. Therefore, change
/sys/bus/firewire/drivers/net
/sys/bus/firewire/devices/fw0.0/driver -> [...]/net
/sys/module/firewire_net/drivers/firewire:net
to
/sys/bus/firewire/drivers/firewire_net
/sys/bus/firewire/devices/fw0.0/driver -> [...]/firewire_net
/sys/module/firewire_net/drivers/firewire:firewire_net
It is redundant but consistent with firewire-sbp2's recently changed
driver name.
I don't see this anywhere used, so it should not matter either way.

Change the log line prefix from "firewire_net: " to
"firewire_net firewire0: " etc. for the case that several RFC 2734
interfaces are being used in the same machine. Despite this addition,
module size is a little bit decreased because KBUILD_MODNAME is now
moved from the format strings into a %s argument.
Note, the kernel's stock functions are not very useful to firewire-net:
dev_notice(&net->dev, "abc\n"); -> net firewire0: abc
netdev_notice(net, "abc\n"); -> firewire_ohci 0000:0a:00.0: firewire0: abc
Nor would be a dev_printk on the fw_unit.device to which firewire-net is
being bound, because there are generally multiple ones of those per
interface (from all RFC 2734 peers on the bus, the local node being only
one of them).
In the initialization message of each interface, log the PCI device
name of the card which is parent of the netdevice instead of the GUID
of the peer which was semi-randomly used to establish the netdevice.

Associate all log messages from firewire-core with the respective card
because some people have more than one card. E.g.
firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0
firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0
firewire_core: created device fw0: GUID 0814438400000389, S800
firewire_core: phy config: new root=ffc1, gap_count=5
firewire_core: created device fw1: GUID 0814438400000388, S800
firewire_core: created device fw2: GUID 0001d202e06800d1, S800
turns into
firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0
firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0
firewire_core 0000:04:00.0: created device fw0: GUID 0814438400000389, S800

firewire_core 0000:05:00.0: created device fw1: GUID 0814438400000388, S800
firewire_core 0000:04:00.0: created device fw2: GUID 0001d202e06800d1, S800
This increases the module size slightly; to keep this in check, turn the
former printk wrapper macros into functions. Their implementation is
largely copied from driver core's dev_printk counterparts.

Why not just "firewireX: " ?

Adding code for the "%s:...", KBUILD_MODNAME rarely saves
overall space. Did you try embedding KBUILD_MODNAME
without the "%s: " and comparing the size?
Perhaps just add pr_fmt and pr_<level>?
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt /* (if really necessary) */
and
#define fwnet_notice(net, fmt, ...) \
pr_notice("%s: " fmt, (net)->name, ##__VA_ARGS__)
#define fwnet_err(net, fmt, ...) \

The double prefix is strangely verbose and pedantic, but it does make
immediately obvious which driver emitted the message (as opposed to one of
the lower-level firewire drivers, or one of the upper-level networking
drivers).
For somebody who is familiar with the drivers --- or after full text search
through the source --- the firewire_net part is of course superfluous.

I think I tried it when I wrote the patch, hence the "module size is a
little bit decreased because KBUILD_MODNAME is now moved from the format
strings into a %s argument" in the changelog. But I wrote this quite a
while ago, so I better try again.
This is on linux-3.2 elf64-x86-64 with a few debug options, gcc-4.5.3.
Before yesterday's patch:
$ size firewire-net.ko; du -b firewire-net.ko
text data bss dec hex filename
9499 744 24 10267 281b firewire-net.ko
209777 firewire-net.ko
With the patch that I posted yesterday:
text data bss dec hex filename
9613 744 24 10381 288d firewire-net.ko
210056 firewire-net.ko
Weird, I must have done something differently back then. Wrongly, for
example.
With module name in the format strings:
#define fwnet_notice(net, fmt, args...) \
printk(KERN_NOTICE KBUILD_MODNAME " %s: " fmt, (net)->name, ## args)
#define fwnet_err(net, fmt, args...) \
printk(KERN_ERR KBUILD_MODNAME " %s: " fmt, (net)->name, ## args)
text data bss dec hex filename
9613 744 24 10381 288d firewire-net.ko
209760 firewire-net.ko
Without the module name, i.e.:
#define fwnet_notice(net, fmt, args...) \
printk(KERN_NOTICE "%s: " fmt, (net)->name, ## args)
#define fwnet_err(net, fmt, args...) \
printk(KERN_ERR "%s: " fmt, (net)->name, ## args)
text data bss dec hex filename
9483 744 24 10251 280b firewire-net.ko
209632 firewire-net.ko
So how about the following patch, for sake of countering kernel bloat?
text data bss dec hex filename
9430 744 24 10198 27d6 firewire-net.ko
209659 firewire-net.ko
--------------------------------- 8< ---------------------------------
Subject: [PATCH 3/4] firewire: net: use dev_printk API
Change the log line prefix from "firewire_net: " to "net firewire0: "
etc. for the case that several RFC 2734 interfaces are being used in the
same machine.
Note, the netdev_printk API is not very useful to firewire-net.
netdev_notice(net, "abc\n") would result in irritating messages like
"firewire_ohci 0000:0a:00.0: firewire0: abc". Nor would a dev_printk on
the fw_unit.device to which firewire-net is being bound be useful,
because there are generally multiple ones of those per interface (from
all RFC 2734 peers on the bus, the local node being only one of them).
In the initialization message of each interface, log the PCI device
name of the card which is parent of the netdevice instead of the GUID
of the peer which was semi-randomly used to establish the netdevice.
