Which means to show any messages -with a level of KERN_ERR or higher severity on the console. - -In practice this often does not result in a quiet boot though, since -there are many false-positive or otherwise harmless error messages printed, -defeating the purpose of the quiet option. Esp. the ACPICA code is really -bad wrt this, but there are plenty of others too. - -This commit makes CONSOLE_LOGLEVEL_QUIET configurable. - -This for example will allow distros which want quiet to really mean quiet -to set CONSOLE_LOGLEVEL_QUIET so that only messages with a higher severity -then KERN_ERR (CRIT, ALERT, EMERG) get printed, avoiding an endless game -of whack-a-mole silencing harmless error messages. - -Acked-by: Steven Rostedt (VMware) <rostedt@goodmis.org> -Signed-off-by: Hans de Goede <hdegoede@redhat.com> ---- - include/linux/printk.h | 6 +++--- - lib/Kconfig.debug | 11 +++++++++++ - 2 files changed, 14 insertions(+), 3 deletions(-) - -diff --git a/include/linux/printk.h b/include/linux/printk.h -index 6d7e800affd8..18602bb3eca8 100644 ---- a/include/linux/printk.h -+++ b/include/linux/printk.h -@@ -50,15 +50,15 @@ static inline const char *printk_skip_headers(const char *buffer) - /* We show everything that is MORE important than this.. */ - #define CONSOLE_LOGLEVEL_SILENT 0 /* Mum's the word */ - #define CONSOLE_LOGLEVEL_MIN 1 /* Minimum loglevel we let people use */ --#define CONSOLE_LOGLEVEL_QUIET 4 /* Shhh ..., when booted with "quiet" */ - #define CONSOLE_LOGLEVEL_DEBUG 10 /* issue debug messages */ - #define CONSOLE_LOGLEVEL_MOTORMOUTH 15 /* You can't shut this one up */ - - /* -- * Default used to be hard-coded at 7, we're now allowing it to be set from -- * kernel config. -+ * Default used to be hard-coded at 7, quiet used to be hardcoded at 4, -+ * we're now allowing both to be set from kernel config. - */ - #define CONSOLE_LOGLEVEL_DEFAULT CONFIG_CONSOLE_LOGLEVEL_DEFAULT -+#define CONSOLE_LOGLEVEL_QUIET CONFIG_CONSOLE_LOGLEVEL_QUIET - - extern int console_printk[]; - -diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug -index 8838d1158d19..0d1c48dd22a9 100644 ---- a/lib/Kconfig.debug -+++ b/lib/Kconfig.debug -@@ -30,6 +30,17 @@ config CONSOLE_LOGLEVEL_DEFAULT - usage in the kernel.
