G'day,

This patch and userspace code are not to be applied, they're just being
posted in case anyone wants to continue this work (Hi Neil!).  They
provide a kernel module and a small userspace program which can be used
as infrastructure for testing various aspects of the sunrpc cache upcall
mechanism.  The kernel module is for SLES10 and thus has several archaic
features like DefineSimpleCacheLookup(), but could be easily ported to
modern code.  Missing are a shell or Python driver to run automated test
cases, and a better way of testing for failure than drawling dmesg. 
However in the absence of those this code has proven useful for a small
amount of manual testing.
