Merge branch 'hfsplus'
Merge hfsplus fixes from Christoph Hellwig: "Two small hfsplus fixes: - a one liner regression fix for large volume handling from Janne Kalliomäki. - a fixup for the boot image blessing feature to make it work with the fake "hardlinks" in hfsplus from Matthew Garrett." * branch 'hfsplus': hfsplus: fix bless ioctl when used with hardlinks hfsplus: fix overflow in sector calculations in hfsplus_submit_bio
