b78ae23fdd - Add "-f file" support to listing mode (-l). When a -f option is

  store are displayed.
- Use MD_NAME instead of "md".

734e78dfcb Disallow attaching preloaded memory disks via ioctl.
- The feature is dangerous because the kernel code didn't check
  validity of the memory address provided from user space.
- It seems that mdconfig(8) never really supported attaching preloaded
  memory disks.
- Preloaded memory disks are automatically attached during md(4)
  initialization. Thus there shouldn't be much use for the feature.

c27a895433 Teach md(4) and mdconfig(8) how to understand XML. Right now there won't be
a problem with listing large number of md(4) devices. Either 'list' or

Additionally, new functionality was introduced. It's possible to pass
multiple devices to -u:

	# ./mdconfig -l -u md0,md1

c313f09bfb When using files as backing stores for devices, and the user has requested the
device be created read+write, check to see if the backing store is read only
through the use of the access(2) system call. If this check fails returning
EACCES, EPERM or EROFS then gracefully downgrade the access to read only. Also
print a warning message to stderr, informing the user that the access mode
they requested is not available.

This behavior used to be handled by md(4) but was changed in revision 1.154
