John Ogness 709fd29a3a printk: wake waiters for safe and NMI contexts ... BugLink: https://bugs.launchpad.net/bugs/1981864 [ Upstream commit 5341b93dea ] When printk() is called from safe or NMI contexts, it will directly store the record (vprintk_store()) and then defer the console output. However, defer_console_output() only causes console printing and does not wake any waiters of new records. Wake waiters from defer_console_output() so that they also are aware of the new records from safe and NMI contexts.
