Help text

Saying Y here will allow you to use create a zoned block device using regular files for zones (one file per zones). This is useful to test file systems, device mapper and applications that support zoned block devices. To create a zoned loop device, no user utility is needed, a zoned loop device can be created (or re-started) using a command like:

echo "add id=0,zone_size_mb=256,capacity_mb=16384,conv_zones=11" > \ /dev/zloop-control

See Documentation/admin-guide/blockdev/zoned_loop.rst for usage details.

If unsure, say N.
