  "message": "printk: Release console_sem after logbuf_lock\n\nRelease console_sem after unlocking the logbuf_lock so that we don\u0027t\ngenerate wakeups while holding logbuf_lock. This avoids some lock\ninversion troubles once we remove the lockdep_off bits between\nlogbuf_lock and rq-\u003elock (prints while holding rq-\u003elock vs doing\nwakeups while holding logbuf_lock).\n\nThere\u0027s of course still an actual deadlock where the printk()s under\nrq-\u003elock will issue a wakeup from the up() call, but lockdep won\u0027t\nwarn about that since semaphores are not tracked.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nLink: http://lkml.kernel.org/n/tip-j8swthl12u73h4znbvitljzd@git.kernel.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
