## NAME
       probe-bcache - probe a bcache device

## SYNOPSIS
       **probe-bcache** [ **-o** _udev_ ] _device_

## OPTIONS
### -o

## USAGE
       Return UUID if device identified as bcache-formatted.

       Only necessary until support for the bcache superblock is included in blkid; in the meantime,
       provides just enough functionality for a udev script to create the /dev/disk/by-uuid symlink.
