Function MakeDeviceID

pkg/abi/linux/dev.go:24–26

MakeDeviceID encodes a major and minor device number into a single device ID. Format (see linux/kdev_t.h:new_encode_dev): Bits 7:0 - minor bits 7:0 Bits 19:8 - major bits 11:0 Bits 31:20 - minor bits 19:8

(major uint16, minor uint32)

// Bits 19:8  - major bits 11:0
// Bits 31:20 - minor bits 19:8

	return (minor & 0xff) | ((uint32(major) & 0xfff) << 8) | ((minor >> 8) << 20)
}

// DecodeDeviceID decodes a device ID into major and minor device numbers.
