[PATCH 00/10] btrfs-progs: check and tune: add device and noscan options

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

By default, btrfstune and btrfs check scans all and only the block devices
in the system.

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

To indicate not to scan the system for other devices, adds 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
        btrfs check --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

        btrfs check --noscan --device /tdev/td1,/tdev/td2 /tdev/td3

 This patch bundle depends on the preparatory patch bundle sent before:
    [PATCH 0/6 v3] btrfs-progs: cleanup and preparatory around device scan

 And, replaces [1] in the mailing list, as the --device option helper
 function is peeled and transformed into a common helper function
 in a separate patch.
