- * the need for a call-back to the ACL system at every point where the mode
- * could change. This function takes the permissions from the specified mode
- * and places it in the supplied ACL.
- *
- * This implementation draws its validity from the fact that, when the ACL
- * was assigned, the mode was copied from the ACL.
- * If the mode did not change, therefore, the mode remains exactly what was
- * taken from the special ACL entries at assignment.
- * If a subsequent chmod() was done, the POSIX spec says that the change in
- * mode must cause an update to the ACL seen at user level and used for
- * access checks. Before and after a mode change, therefore, the file mode
- * most accurately reflects what the special ACL entries should permit/deny.
- *
- * CAVEAT: If someone sets the SGI_ACL_FILE attribute directly,
- * the existing mode bits will override whatever is in the
- * ACL. Similarly, if there is a pre-existing ACL that was
- * never in sync with its mode (owing to a bug in 6.5 and
- * before), it will now magically (or mystically) be
- * synchronized. This could cause slight astonishment, but
- * it is better than inconsistent permissions.
- *
- * The supplied ACL is a template that may contain any combination
- * of special entries. These are treated as place holders when we fill
- * out the ACL. This routine does not add or remove special entries, it
- * simply unites each special entry with its associated set of permissions.
