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 <danieru.dressler@gmail.com> Signed-off-by: David Sterba <dsterba@suse.cz>
