From b7a0365ec7a0fb1d39113846fd34038af68ebd01 Mon Sep 17 00:00:00 2001 From: Daniel Dressler Date: Wed, 12 Nov 2014 13:43:09 +0900 Subject: Btrfs: ctree: reduce args where only fs_info used This patch is part of a larger project to cleanup btrfs's internal usage of struct btrfs_root. Many functions take btrfs_root only to grab a pointer to fs_info. This causes programmers to ponder which root can be passed. Since only the fs_info is read affected functions can accept any root, except this is only obvious upon inspection. This patch reduces the specificty of such functions to accept the fs_info directly. This patch does not address the two functions in ctree.c (insert_ptr, and split_item) which only use root for BUG_ONs in ctree.c This patch affects the following functions: 1) fixup_low_keys 2) btrfs_set_item_key_safe Signed-off-by: Daniel Dressler Signed-off-by: David Sterba --- fs/btrfs/file-item.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/btrfs/file-item.c') diff --git a/fs/btrfs/file-item.c b/fs/btrfs/file-item.c index 84a2d1868271..fc003321bdd4 100644 --- a/fs/btrfs/file-item.c +++ b/fs/btrfs/file-item.c @@ -553,7 +553,7 @@ static noinline void truncate_one_csum(struct btrfs_root *root, btrfs_truncate_item(root, path, new_size, 0); key->offset = end_byte; - btrfs_set_item_key_safe(root, path, key); + btrfs_set_item_key_safe(root->fs_info, path, key); } else { BUG(); } -- cgit v1.2.3
