[BusyBox-cvs] CVS update of busybox/util-linux (fdisk.c)

Erik Andersen andersen at codepoet.org
Mon Jun 28 23:50:32 UTC 2004


    Date: Monday, June 28, 2004 @ 17:50:32
  Author: andersen
    Path: /var/cvs/busybox/util-linux

Modified: fdisk.c (1.25 -> 1.26)

Avoid a number of places where large drives could wrap a uint, and
instead use off_t which will be automagically promoted to 64bit if
compiled with support for large drives.
 -Erik
