[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 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.

The stand-alone patch as-is currently doesn't apply to bpf-next.
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.
