From f76d28d235cf777dd2e1c1d48c16ee10c1d1587f Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Mon, 1 Aug 2005 21:11:40 -0700 Subject: [PATCH] hfs: don't dirty unchanged inode If inode size hasn't changed, don't do anything further in truncate, which also prevents a dirty inode, what might upset some readonly devices quite badly.
