Prefer psame_inode, PSAME_INODE, STP_NBLOCKS, and STP_BLKSIZE, which take addresses of objects, to their counterparts that take the whole objects. In some cases the whole objects might not be initialized, which would be undefined behavior strictly speaking. * gl/lib/root-dev-ino.h (ROOT_DEV_INO_CHECK): * src/cp-hash.c (src_to_dest_compare): * src/ls.c (dev_ino_compare): * src/pwd.c (robust_getcwd): Prefer PSAME_INODE to SAME_INODE. * src/chown-core.c (restricted_chown): * src/copy.c (copy_reg, same_file_ok, source_is_dst_backup) (copy_internal): * src/ln.c (do_link): * src/pwd.c (logical_getcwd): * src/sort.c (avoid_trashing_input): * src/split.c (create): * src/stat.c (find_bind_mount): Prefer psame_inode to SAME_INODE. * src/copy.c (infer_scantype): * src/du.c (process_file): * src/ls.c (gobble_file, print_long_format) (print_file_name_and_frills, length_of_file_name_and_frills): * src/stat.c (print_stat): Prefer STP_NBLOCKS to ST_NBLOCKS. * src/copy.c (copy_reg): * src/head.c (elide_tail_bytes_file, elide_tail_lines_file): * src/ioblksize.h (io_blksize): * src/od.c (skip): * src/shred.c (do_wipefd): * src/stat.c (print_stat): * src/tail.c (tail_bytes): * src/truncate.c (do_ftruncate): * src/wc.c (wc): Prefer STP_BLKSIZE to ST_BLKSIZE. * src/ioblksize.h (io_blksize): Arg is now struct stat const *, not struct stat. All callers changed.
