From ad25ad979a309963e580015d57e4ec7da72bb7d4 Mon Sep 17 00:00:00 2001 From: Evgeniy Dushistov Date: Wed, 10 Mar 2010 15:21:55 -0800 Subject: ufs: make solaris fsck happy Alex Viskovatoff let me know that after copying data to solaris's ufs from linux, solaris's fsck sees some errors in cylinder summary information. This is because of solaris expects find some data on another places, then curernt implementation save it. This patch fixes this issue. It is tested by me, and also Alex reported that it works for him.
