btrfs balance needs --full-balance option since 4.6, so check the version and then use it. As this may be useful for other btrfs tests as well, so this patch also adds _run_btrfs_balance_start() to the common/btrfs file. Signed-off-by: Anand Jain <anand.jain@oracle.com> --- v2: Use help to find if --full-balance is supported Make a local variable run the balance instead of getting the options common/btrfs | 11 +++++++++++ tests/btrfs/124 | 2 +- 2 files changed, 12 insertions(+), 1 deletion(-)
