Merge tag 'uuid-for-4.13' of git://git.infradead.org/users/hch/uuid into overlayfs-next
UUID/GUID updates: - introduce the new uuid_t/guid_t types that are going to replace the somewhat confusing uuid_be/uuid_le types and make the terminology fit the various specs, as well as the userspace libuuid library. (me, based on a previous version from Amir) - consolidated generic uuid/guid helper functions lifted from XFS and libnvdimm (Amir and me) - conversions to the new types and helpers (Amir, Andy and me)
