Hi Volodymyr,

The patch which I suggested in the thread which you referenced was
intended to debug the bug to find the real root cause of the issue.
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?
