(2). no-limitation will show 'none'. qgroupid rfer excl max_rfer max_excl parent -------- ---- ---- -------- -------- ------ 0/5 2.19GiB 2.19GiB none none --- 0/257 100.02MiB 100.02MiB none none --- Signed-off-by: Dongsheng Yang <[email protected]> --- qgroup.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/qgroup.c b/qgroup.c index 53815b5..dc04b03 100644 --- a/qgroup.c +++ b/qgroup.c @@ -237,10 +237,16 @@ static void print_qgroup_column(struct btrfs_qgroup *qgroup, print_qgroup_column_add_blank(BTRFS_QGROUP_PARENT, len); break; case BTRFS_QGROUP_MAX_RFER: - len = printf("%*s", max_len, pretty_size_mode(qgroup->max_rfer, unit_mode)); + if (qgroup->flags & BTRFS_QGROUP_LIMIT_MAX_RFER) + len = printf("%*s", max_len, pretty_size_mode(qgroup->max_rfer, unit_mode)); + else + len = printf("%*s", max_len, "none"); break; case BTRFS_QGROUP_MAX_EXCL: - len = printf("%*s", max_len, pretty_size_mode(qgroup->max_excl, unit_mode)); + if (qgroup->flags & BTRFS_QGROUP_LIMIT_MAX_EXCL) + len = printf("%*s", max_len, pretty_size_mode(qgroup->max_excl, unit_mode)); + else + len = printf("%*s", max_len, "none"); break; case BTRFS_QGROUP_CHILD: len = print_child_column(qgroup); -- 1.8.4.2 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
