source: patches/util-linux-2.12r-cramfs-1.patch@ a8f30b25

Submitted by: Jeremy Utley <jeremy@linuxfromscratch.org>
Date: 2004-12-25
Initial Package Version: 2.12p (should apply to versions back to at least k)
Upstream Status: Not Submitted - Test Version
Origin: Alexander Patrakov, adapted from debian build of cramfs utilities
Description: Util-Linux fails in cramfs compilation due to changes in the
linux-libc-headers package 2.6.9 and after.  This patch is a proper fix to the
problem, but may in fact not be accepted upstream.
