Module storage 

Block-device and queue-discovery utilities.

The helpers inspect filesystem metadata and system block-device information. Discovery covers backing device names, software RAID, and multi-queue properties.

Discovery reads sysfs under /sys/dev/block/ and stats the device through MetadataExt, neither of which exists outside the unix family. On non-unix targets these functions report no raid or return an unsupported error, so callers need no condition of their own.

Structs

MultiDevice

Multi-Device (md) i.e. software raid properties.

MultiQueue

Multi-Queue (mq) characteristics.

Queue

Single-queue characteristics
