Oh, after ZUFS GC patches, we have six parameters on that. You're right.

static int do_garbage_collect(struct f2fs_sb_info *sbi,
                                unsigned int start_segno,
                                struct gc_inode_list *gc_list, int gc_type,
                                bool force_migrate)
