Merge tag 'uuid-for-4.13' of git://git.infradead.org/users/hch/uuid
Pull uuid subsystem from Christoph Hellwig: "This is the new uuid subsystem, in which Amir, Andy and I have started consolidating our uuid/guid helpers and improving the types used for them. Note that various other subsystems have pulled in this tree, so I'd like it to go in early. UUID/GUID summary: - 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)" * tag 'uuid-for-4.13' of git://git.infradead.org/users/hch/uuid: (34 commits) ACPI: hns_dsaf_acpi_dsm_guid can be static mmc: sdhci-pci: make guid intel_dsm_guid static uuid: Take const on input of uuid_is_null() and guid_is_null() thermal: int340x_thermal: fix compile after the UUID API switch thermal: int340x_thermal: Switch to use new generic UUID API acpi: always include uuid.h ACPI: Switch to use generic guid_t in acpi_evaluate_dsm() ACPI / extlog: Switch to use new generic UUID API ACPI / bus: Switch to use new generic UUID API ACPI / APEI: Switch to use new generic UUID API acpi, nfit: Switch to use new generic UUID API MAINTAINERS: add uuid entry tmpfs: generate random sb->s_uuid scsi_debug: switch to uuid_t nvme: switch to uuid_t sysctl: switch to use uuid_t partitions/ldm: switch to use uuid_t overlayfs: use uuid_t instead of uuid_be fs: switch ->s_uuid to uuid_t ima/policy: switch to use uuid_t ...
