- * #define S_IFREG  0100000  type = regular file
- * #define S_IFBLK  0060000  type = block device
- * #define S_IFDIR  0040000  type = directory
- * #define S_IFCHR  0020000  type = character device
- * #define S_IFIFO  0010000  type = named pipe
- * #define S_ISUID  0004000  set user id
- * #define S_ISGID  0002000  set group id
- * #define S_ISVTX  0001000  save swapped text even after use
- * Additionally for SystemV:
- * #define S_IFLNK  0120000  type = symbolic link
- * #define S_IFNAM  0050000  type = XENIX special named file ??
- * Additionally for Coherent:
- * #define S_IFMPB  0070000  type = multiplexed block device ??
- * #define S_IFMPC  0030000  type = multiplexed character device ??
- *
- * Since Coherent doesn't know about symbolic links, we use a kludgey
- * implementation of symbolic links: i_mode = COH_KLUDGE_SYMLINK_MODE
- * denotes a symbolic link. When a regular file should get this mode by
- * accident, it is automatically converted to COH_KLUDGE_NOT_SYMLINK.
- * We use S_IFREG because only regular files (and Coherent pipes...) can have
- * data blocks with arbitrary contents associated with them, and S_ISVTX
- * ("save swapped text after use") because it is unused on both Linux and
- * Coherent: Linux does much more intelligent paging, and Coherent hasn't
- * virtual memory at all.
- * Same trick for Xenix.
