Merge branch 'liblockdep-fixes-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux into core/urgent

Pull a liblockdep fix from Sasha Levin:

 "A small (but important) fix to the way we detect freeing live locks. We would
  pass a wrong memory region when testing for locks inside freed memory spaces,
  which would trigger false positives."
