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." Signed-off-by: Ingo Molnar <mingo@kernel.org>
