[PATCH v2 00/33] Kill pr_warning in the whole linux code

[PATCH v2 00/33] Kill pr_warning in the whole linux code

[Kefeng Wang]

There are pr_warning and pr_warng to show WARNING level message,
most of the code using pr_warn, number based on next-20191017,

pr_warn: 5206   pr_warning: 546 (tools: 399, others: 147)

Joe Perches posted a patch, commit f2c2cbcc35d4 ("powerpc: Use
pr_warn instead of pr_warning"), which is beginning to remove
pr_warning, so all logging messages use a consistent pr_warn
style once pr_warning removed, and checkpatch also sugguests
that better to use pr_warn instead of pr_warning.

Let's carry on with the work to standardize the logging macro,
kill pr_warning in the whole linux code.

Note, for tools api/bpf/perf part, rename pr_warning to pr_warn
to keep the consistence, with this patchset,

pr_warn: 5747   pr_warning: 0

Patch[01-28]: simply sed and ajust formats
patch[29]:    drop pr_warning definition in printk
patch[30-32]: tools api/bpf/perf, rename and make manually changes
patch[33]:    cleanup the checkpatch.pl

Miscellanea:
o Coalesce formats
o Realign arguments
o Remove unnecessary line continuations

The patchset is based on next-20191017 and will be taked via printk.git
by Petr Mladek, see
https://lore.kernel.org/lkml/20191017135229.a4mvcyap6l34m5bk@pathway.suse.cz/

v2:
- Collect ack-by/review-by
- Fix some indentation and alignment 
- Split patches in drivers/platform/x86/ suggested by Andy Shevchenko
- Drop staging changes which already merged

[PATCH v2 05/33] sh: Use pr_warn instead of pr_warning

[Kefeng Wang]

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of
pr_warning"), removing pr_warning so all logging messages use a
consistent <prefix>_warn style. Let's do it.

[PATCH v2 08/33] acpi: Use pr_warn instead of pr_warning

[Kefeng Wang]

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of
pr_warning"), removing pr_warning so all logging messages use a
consistent <prefix>_warn style. Let's do it.

[PATCH v2 15/33] macintosh: Use pr_warn instead of pr_warning

[Kefeng Wang]

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of
pr_warning"), removing pr_warning so all logging messages use a
consistent <prefix>_warn style. Let's do it.

to kernel logging macro, then we could drop pr_warning in the

[PATCH v2 32/33] tools perf: Renaming pr_warning to pr_warn

[Kefeng Wang]

For kernel logging macro, pr_warning is completely removed and
replaced by pr_warn, using pr_warn in tools perf for symmetry
to kernel logging macro, then we could drop pr_warning in the
whole linux code.

Nack.
I prefer this type of renaming to go via bpf tree.
It's not a kernel patch. It's touching user space library
which is under heavy development.
Doing any other way will cause a ton of conflicts.

Fair enough. I'll ignore this patch. Could I assume that it will
be taken via bpf tree, please?

I'll also postpone the patch that removes pr_warning() to avoid
synchronization problems. I'll push it later when changes in
bpf[*] subsystem are merged.

[*] I am going to check conflicts against 5.4-rc1. I'll probably
ask more subsystems to take their changes to avoid conflicts
and make it smooth.

All these patches have been commited in printk.git,
branch for-5.5-pr-warn.

I'll wait with these two until I am sure that the are no
pr_warning() users in linux-next.


> patch[30-32]: tools api/bpf/perf, rename and make manually changes

Only the tool api patch is commited in printk.git.

The other two (bpf and perf) will need to go via the related
subsystems to avoid conflicts nightmare. The good thing is
that these are userspace tools. They do not block removing
pr_warning() from the internal kernel API.

Could you spin a fresh rebase and resubmit?

[bpf-next] tools lib bpf: Renaming pr_warning to pr_warn

[Kefeng Wang]

For kernel logging macro, pr_warning is completely removed and
replaced by pr_warn, using pr_warn in tools lib bpf for symmetry
to kernel logging macro, then we could drop pr_warning in the
whole linux code.
