New patch to solve problem

The original patch caused compiler warnings on build.  The attached patch
compiles cleanly.  Can the reporter please test this patch to verify that the
problem is solved with it.

Please follow up on this immediately, or the fix will miss U7.  Thanks.

Comment 16 Ernie Petrides 2005-11-30 07:34:08 UTC
A fix for this problem has just been committed to the RHEL3 U7
patch pool this evening (in kernel version 2.4.21-37.12.EL).
