[PATCH 0/4] btrfs-progs: tune: add --device and --noscan option

[Anand Jain <anand.jain@oracle.com>]

Separated out from the preparatory patch set. Depends on the preparatory
patch set: ("btrfs-progs: cleanup and preparatory around device scan").
This set (along with its preparatory patch) has passed the btrfs-progs
test suite.

By default, btrfstune scans all the block devices in the system.

To scan regular files without mapping them to a loop device, add the
--device option.

The option arguments follow the same pattern as in the "mkfs.btrfs -O"
option.

To indicate not to scan the system for other devices, add the --noscan
option.

For example:

  The command below will scan both regular files and the devices
  provided in the --device option, along with the system block devices.

	btrfstune -m --device /tdev/td1,/tdev/td2 /tdev/td3
  or
	btrfstune -m --device /tdev/td1 --device /tdev/td2 /tdev/td3

  In some cases, if you need to avoid the default system scan for the
  block device, you can use the --noscan option.

	btrfstune -m --noscan --device /tdev/td1,/tdev/td2 /tdev/td3
