Hi,
Stanse found unreachable code in btrfs_insert_some_items below (don't
look at the line numbers, they are on preprocessed code). I would fix
that if I knew how.
Should the assignment be after the if, before the break or nowhere?
3068|int btrfs_insert_some_items(struct btrfs_trans_handle *trans,
3069| struct btrfs_root *root,
3070| struct btrfs_path *path,
3071| struct btrfs_key *cpu_key, u32 *data_size,
3072| int nr)
3073|{
...
3086| for (i = 0; i < nr; i++) {
3087| if (total_size + data_size[i] + sizeof(struct btrfs_item) >
3088| (((root->leafsize) - sizeof(struct btrfs_header)))) {
3089| break;
3090| nr = i;
|This node is unreachable prev next
3091| }
3092| total_data += data_size[i];
3093| total_size += data_size[i] + sizeof(struct btrfs_item);
3094| }
regards,
