One other observeration; problems relating to tid wrap have been
around for a very long time.  It's an issue for both ext3 and ext4, so
Red Hat and SuSE have been shipping QA'ed enterprise kernels with this
issue for over a decade.  This is one of the reasons why I don't think
it's a good idea to rush a fix into mainline, the stable 3.2.x
kernels, or the Debian kernel, until we really make sure we have any
proposed bug fixes fully tested and verified.
