NAME
     md - memory disk driver

SYNOPSIS
     pseudo-device md

DESCRIPTION

     kernel options MEMORY_DISK_HOOKS, MEMORY_DISK_IS_ROOT,
     MEMORY_DISK_ROOT_SIZE, MEMORY_DISK_DYNAMIC, and MEMORY_DISK_SERVER.

FILES
     /dev/md??   block mode memory disk devices.
     /dev/rmd??  raw mode memory disk devices.
