    Btrfs: implement online profile changing · e4d8ec0f
    Ilya Dryomov authored
    Profile changing is done by launching a balance with
    BTRFS_BALANCE_CONVERT bits set and target fields of respective
    btrfs_balance_args structs initialized.  Profile reducing code in this
    case will pick restriper's target profile if it's available instead of
    doing a blind reduce.  If target profile is not yet available it goes
    back to a plain reduce.
