Ran: generic/077
Failures: generic/077
Failed 1 of 1 tests
Reason:
btrfs progs v4.3 use non-mixed blockgroup for small volume as default,
it need at least 100M to build a filesystem.
Fix:
Force mixed mode for small-size fs, to make mkfs success.
Changelog v1->v2:
Use mixed mode for small-size fs, instead of increase test fs size
in v1.
