From 442244c9633292a147ab2b29e7007a7c8a3909b2 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Thu, 16 Apr 2015 17:18:36 +0800 Subject: [PATCH] btrfs: qgroup: Switch self test to extent-oriented qgroup mechanism. Since the self test transaction don't have delayed_ref_roots, so use find_all_roots() and export btrfs_qgroup_account_extent() to simulate it Signed-off-by: Qu Wenruo Signed-off-by: Chris Mason --- fs/btrfs/qgroup.c | 2 +- fs/btrfs/qgroup.h | 5 ++ fs/btrfs/tests/qgroup-tests.c | 109 ++++++++++++++++++++++++++++++++---------- 3 files changed, 89 insertions(+), 27 deletions(-) diff --git a/fs/btrfs/qgroup.c b/fs/btrfs/qgroup.c index 70c366f..693533d 100644 --- a/fs/btrfs/qgroup.c +++ b/fs/btrfs/qgroup.c @@ -2455,7 +2455,7 @@ static int btrfs_qgroup_account(struct btrfs_trans_handle *trans, return ret;
