Subject: [GIT PULL] lockdep fix
Date: Sat, 11 Feb 2017 19:09:19 +0100	[thread overview]
Message-ID: <20170211180918.GA6174@gmail.com> (raw)

Linus,

Please pull the latest locking-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking-urgent-for-linus

   # HEAD: bfeda41d06d85ad9d52f2413cfc2b77be5022f75 stacktrace, lockdep: Fix address, newline ugliness

This fixes an ugly lockdep stack trace output regression. (But also affects other 
stacktrace users such as kmemleak, KASAN, etc.)

 Thanks,

	Ingo
