Subject: JFFS2 node versioning problem?
Date: Wed, 3 May 2006 15:56:37 +0400 [thread overview]
Message-ID: <200605031556.37660.atrey@emcraft.com> (raw)
Hello everybody!
I was just thinking about hypothetical situation with JFFS2 wich possibly
could be met in the reality. What happens when the highest node version of a
certain inode exceeds the maximum value?
I think this can be a point where the inode can be broken. If there are two
data nodes which have overlapped regions and more recent node has a lesser
value then the other node has, then, when the partition is dismounted and
mounted again the more recent inode is treated as an older one and could be
obsoleted. Even if it is not obsoleted, its data become superseeded by data
from the least recent node as the last one has a higher version number.
