+Subject: [PATCH 120/134] lockdep: Mark emergency section in lockdep splats
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
+
+Mark an emergency section within print_usage_bug(), where
+lockdep bugs are printed. In this section, the CPU will not
+perform console output for the printk() calls. Instead, a
+flushing of the console output will triggered when exiting
+the emergency section.
