Linus,
please re-pull
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/linux-2.6-lockdep.git v2.6.24-lockdep
[ I just commited the two new patches to the end of the branch you
pulled before, and assumed git will be smart enough to not try and
again merge the patches you pulled before ]
in order to receive:
Peter Zijlstra (2):
lockdep: fixup the inode dir annotation
lockdep: fix fault vs irq tracing
