Merge tag 'printk-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek: - Remove some twists in the console registration code. It does not change the existing behavior except for one corner case. The proper default console (with tty binding) will be registered again even when it has been removed in the meantime. It is actually a bug fix. Anyway, this modified behavior requires some manual interaction. - Optimize gdb extension for huge ring buffers. - Do not use atomic operations for a local bitmap variable. - Update git links in MAINTAINERS. * tag 'printk-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: MAINTAIERS/printk: Add link to printk git MAINTAINERS/vsprintf: Update link to printk git tree scripts/gdb: lx-dmesg: read records individually printk/console: Clean up boot console handling in register_console() printk/console: Remove need_default_console variable printk/console: Remove unnecessary need_default_console manipulation printk/console: Rename has_preferred_console to need_default_console printk/console: Split out code that enables default console vsprintf: Use non-atomic bitmap API when applicable
