+Subject: [PATCH 296/323] printk: Enhance the condition check of msleep in
+ pr_flush()
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+[ Upstream commit 83e9288d9c4295d1195e9d780fcbc42c72ba4a83 ]
+
+There is msleep in pr_flush(). If call WARN() in the early boot
+stage such as in early_initcall, pr_flush() will run into msleep
+when process scheduler is not ready yet. And then the system will
+sleep forever.
+
+Before the system_state is SYSTEM_RUNNING, make sure DO NOT sleep
+in pr_flush().
+
+Fixes: c0b395bd0fe3("printk: add pr_flush()")
