- * In the non-POSIX case, we transform each character into a string of
- * characters representing the character's priority.  Since char is usually
- * signed, we are limited by 7 bits per byte.  To avoid zero, we need to add
- * XFRM_OFFSET, so we can't use a full 7 bits.  For simplicity, we choose 6
- * bits per byte.  We choose 4 bytes per character as a good compromise
- * between maximum coverage and minimum size.  This gives 24 bits, or 16M
- * priorities.  So we choose COLLATE_MAX_PRIORITY to be (2^24 - 1).  This
- * this can be increased if more is needed.
