commit38d51b2dd1upstream. Dan Carpenter reported the following static checker warning. fs/ocfs2/super.c:1269 ocfs2_parse_options() warn: '(-1)' 65535 can't fit into 32767 'mopt->slot' fs/ocfs2/suballoc.c:859 ocfs2_init_inode_steal_slot() warn: '(-1)' 65535 can't fit into 32767 'osb->s_inode_steal_slot' fs/ocfs2/suballoc.c:867 ocfs2_init_meta_steal_slot() warn: '(-1)' 65535 can't fit into 32767 'osb->s_meta_steal_slot' That's because OCFS2_INVALID_SLOT is (u16)-1. Slot number in ocfs2 can be never negative, so change s16 to u16.
