[PATCH 0/2] printk: Add loud_console printk flag to not suppress sysrq header msgs

Posted by Marcos Paulo de Souza 1 month, 1 week ago

Hello,

These two patches will change printk_context to store a new context,
called loud console. By using this context it would be possible to have
printk messages that are never suppressed by loglevel filtering.

This is useful on __handle_sysrq that currently uses a workaround to
make sure that sysrq header message are not suppressed.

Please review!
