Comment about interesting interlocking between lockbuf_lock and console_sem is outdated. It was added in 2002 by commit a880f45a48be during conversion of console_lock to console_sem + lockbuf_lock. At that time release_console_sem() (today's equivalent is console_unlock()) was indeed using lockbuf_lock to avoid races between trylock on console_sem in printk() and unlock of console_sem. However these days the interlocking is gone and the races are avoided by rechecking logbuf state after releasing console_sem.
