As long as we've purged all kernelspace flag updates it's probably ok to "accidentally" mount ext2 (or ext3) as ext4 - as long as it's really easy to go back. It'd be worth one more look though in the long run. Early on I had some nasty surprises with ext4 "assimilating" my ext3 RHEL5 root disk :) -Eric > I'll rework my patch and send out an update when it's ready. > > Thanks again! > > PeterK > -- > To unsubscribe from this list: send the line "unsubscribe linux-ext4" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
