<action> is one of:
	format <integrity_device> - format device
	open <integrity_device> <name> - open device as <name>
	close <name> - close device (remove mapping)
	status <name> - show active device status
	dump <integrity_device> - show on-disk information
	resize <name> - resize active device

<name> is the device to create under /dev/mapper
<integrity_device> is the device containing data with integrity tags

Default compiled-in dm-integrity parameters:
	Checksum algorithm: crc32c
	Maximum keyfile size: 4kB
