[PATCH v3 0/2] MR9732: ntdll: Support FSCTL_DUPLICATE_EXTENTS_TO_FILE

[nikita pushkarev (＠strudelll)]

Implement FSCTL_DUPLICATE_EXTENTS_TO_FILE handling in ntdll on Linux by wiring the IOCTL to FICLONERANGE/FICLONE where available and returning STATUS_INVALID_DEVICE_REQUEST otherwise. Adds the necessary constants/types when missing.
