If in fact the WARN() is triggering on your 3.0 system, then there's a bug that we should be trying to fix. Instead of using this patch to paper over the problem, I'd much rather see if we can figure out why jinode was NULL in the first place. Can you reliably reproduce this failure? Regards, - Ted
