  "message": "[PATCH] lockdep: fix printk recursion logic\n\nBug reported and fixed by Tilman Schmidt \u003ctilman@imap.cc\u003e: if lockdep is\nenabled then log messages make it to /var/log/messages belatedly.  The\nreason is a missed wakeup of klogd.\n\nInitially there was only a lockdep_internal() protection against lockdep\nrecursion within vprintk() - it grew the \u0027outer\u0027 lockdep_off()/on()\nprotection only later on.  But that lockdep_off() made the\nrelease_console_sem() within vprintk() always happen under the\nlockdep_internal() condition, causing the bug.\n\nThe right solution to remove the inner protection against recursion here -\nthe outer one is enough.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Tilman Schmidt \u003ctilman@imap.cc\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
