From a7fe0ba7eee4f7c53077ff2bed2b581db17d00df Mon Sep 17 00:00:00 2001 From: Shaun Zinck Date: Fri, 31 Aug 2007 12:57:28 -0500 Subject: JFS: use DIV_ROUND_UP where appropriate This replaces some macros and code, which do the same thing as DIV_ROUND_UP defined in kernel.h, to use the DIV_ROUND_UP macro.
