From b0b623c3b22d57d6941b200321779d56c4e79e6b Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Tue, 29 Nov 2005 19:34:41 -0800 Subject: [PATCH] hfsplus: don't modify journaled volume Access to a journaled HFS+ volume is not officially supported under Linux, so mount such a volume read-only, but users can override this behaviour using the "force" mount option. The minimum requirement to relax this check is to at least check that the journal is empty and so nothing needs to be replayed to make sure the volume is consistent.
