Subject: [PATCH v2 0/3] printk: introduce new macros pr_<level>_cont()
Date:   Fri, 25 Nov 2022 20:09:45 +0100

This series adds new printk wrapper macros pr_<level>_cont().
These create continuation messages with an explicit level.

Explicit levels are useful when a continuation message is split from its main
message. Without the explicit level KERN_DEFAULT ("warn" by default) is used
which can lead to stray partial log messages when filtering by level.

Also checkpatch is modified to recommend the new macros over plain pr_cont().

Lastly the new macros are used in kernel/power/process.c as this file uses
continuation messages during system suspend-resume which creates a high
likelyhood of interspersed messages.

Changelog:

This was original a single patch but was expanded into a series.

v1: https://lore.kernel.org/lkml/20221121050946.3540-1-linux@weissschuh.net/
v1 -> v2:
  * Introduce new pr_<level>_cont() macros in printk.h
  * Add checkpatch.pl validation

Thomas Weißschuh (3):
  printk: introduce new macros pr_<level>_cont()
  checkpatch: handle new pr_<level>_cont macros
  power: process: use explicit levels for printk continuations
